The Big Magnum 5.2/5.9 Swap Wiring Guide! How To Wire A Magnum In Your Old Mopar (Or Anything Else)

[@BruceAsher-u9x]

I figured this out about eight years ago using a 5.2 from a 96 jeep grand cherokee. I wired it up and could get it to start, but it would die within a couple of seconds. I finally decided to pull the body control module and wire in the data link wires, and it fired right up.

Fantastic video. I'm so grateful for the information.

[@autopar3000]

Jamie, this is great content. I had to figure all of this out on my own when I did mine, so I'm sure this will help tons of people. I want to share a few notes / experiences: 1. Fuel pressure regulator. I used a filter / regulator for a 2002 Cherokee. It runs at 52 psi, which is supposed to be too much for my OBD1 setup's needs, but it runs perfect in my setup. Would be totally fine for an OBD2 swap with its higher pressure spec. 2. Speed sensor. I have also run thousands of miles without one. From day 1 my car was popping through the exhaust a bit on deceleration. The car sounded like a douchemobile on deceleration, and I couldn't figure out why. It has the Hughes SER0814ALN-14 cam and long tube headers, so I thought maybe it's breathing better than the PCM expects it should. Then I added the speed sensor from a 93 Dakota to control OD and lockup on my 46rh (I was using switches for that previously). The Dakota VSS has the output for my mechanical speedo, and is only 2 wire: one to ground, the other to the PCM. Super easy. The minute I added the VSS the car stopped popping through the exhaust on deceleration. I later learned that the PCM tells the IAC to open up a bit on deceleration, which prevents the popping. 3. ASD relay. I didn't put in an ASD relay. I think I just wired that circuit through the ignition switch. Your video helped me realize that's a problem I should fix ASAP!

[@DeadDodgeGarage]

Awesome! Bypassing the ASD definitely could work, but it throws a code and I feel like there are good reasons to have it there. Good to know on speed sensor! I know it does *something*. Haha. Good to know the Cherokee used a filter regulator. I had no idea. I tried using the GM filter regulator in my first swap. It didn’t work right… then I found out the one I had tried didn’t actually have a regulator? Something weird like that.

[@TheAndrescan]

I need to try this. my swap also backfires on decel and I have no VSS. thanks for the info.

LOL In my case the Dakota still would start and run after I unplugged so I was really confused why it was there.

[@DeadDodgeGarage]

Thank you! It’s what the people have wanted for a long time! Haha. Very good to know it would start without it. I had read that some applications won’t, so I’ve always just installed them, but I really don’t know. Haven’t tried without on any myself.

[@DeadDodgeGarage]

I’ve been confused before, but I’m really quite confused right now 😅

[@justme-n-gracie]

On my 97 truck the VSS signal is used to control the OD in the trans via the ECM/PCM. My 97 also has a CPS/Crankshaft Position Sensor. It's at the top of the bellhousing. As far as I can tell, the CPS signal is used by the ECM/PCM to disable/shut off the ASD relay if the engine stops turning. When this sensor (or the connection to it) goes bad the engine will start then shut off. One plug that I know is different between my 94 and 97 trucks is the IAC/Idle Air Control solenoid that controls idle speed. I was swapping throttle bodies and had to swap the IAC as well.

[@DeadDodgeGarage]

1) At least on newer systems, overdrive (and lockup) will engage with *no* VSS signal. And I know that because I’ve done hundreds of miles in overdrive in a swapped vehicle with no VSS whatsoever. It did have some other odd issues that may or may not have been related. I can’t speak specifically to ‘97. 2) the crankshaft position sensor is used for a lot more than that. It is actually used as a basis to time spark events, and may figure into fuel timing. I am not 100% sure of this. Indeed, the ASD and fuel pump relay are “primed” at key on, and then activated when the PCM detects that the engine is turning. The starts-and-dies issues cannot *necessarily* be attributed to a bad crank sensor, because if it starts at all, it at least briefly had a spark timing signal. I would be more suspicious of the distributor pickup. 3) around ‘97/98, *all* of the sensor plugs changed styles. I’m not sure why they did this, and early and late sensors are all functionally interchangeable with a connector swap.

I have been wanting to Magnum swap a car for the last 15 years!!! My biggest issues were transmission and wiring: either cutting the floor for an 42/46RH/E and/or nothing super easy or cost effective for an 833/OD and then the rat's nest of extra wiring, internet folks saying how easy it is, but leaving out some key pointers (some folks, not all folks - it was mostly me...I'll admit it). But here comes Dead Dodge Garage to answer ALL my questions and address my fears! My 833OD is already swapped and coming up with a 318LA flywheel to modify for the tone ring/flex plate is also secured. I have a 94 5.2 out of a van and a 94 5.9 out of a truck. Yes, they're OBD1....so, my question, is this a MAJOR drawback or, because I already have all the stuff, should I just use what I have? Thanks Jamie!!!

I've never done one of these, but I have done 5-6 Fox Mustang 5.0 H.O. EFI swaps into various cars. It's interesting how similar most of the information is; OBD-2 is obviously more complex than the OBD-1 systems I'm used to, but not that much more. Like the Magnum swap, the H.O. has maybe five wires total under the dash to make everything work, and the harness is pretty much stand-alone. Now I'm daydreaming about this green '70 Scamp I know of for sale.

[@DeadDodgeGarage]

Yep! I meant to make a note that this is really, really similar to other EFI systems. I’ve never wired the 5.0, but I kinda know what makes it tick. That’s a good one.

Friggin awesome video dude. Now do an OBD1 LOL. I’m looking at swapping a 93 5.9 into my 89 W150 5.2

[@DeadDodgeGarage]

Like I said, all of the important wiring you’ll need to add is the same. Hell the color codes on the wires are usually the same even… ‘93 being the last year of the old body style, I don’t really know what your donor wiring is going to look like - but given that you’re building an ‘89, I’d probably just take all of it and swap it over. That may be your easiest course. But I did the same basic thing on my van - I removed all of the TBI stuff, added a later truck harness (OBD2, again) and just used the wires from the original TBI engine that I needed.

Great video, very helpful. when I was pulling my donor out of a 01 1500 I noticed a device on the rear of the block that looks a lot like a crank sensor running off of the flywheel of the donor engine. What is that devise, I am hoping it is for the trans input. second question: I plan on putting this in a 77 dually plow truck with a 4 speed, any experience with installing this magnum 5.9 in a standard trans? and last but not least I can not find the diagrams you stated would be linked to the video.

[@DeadDodgeGarage]

I put links to a couple diagrams in the description but I couldn’t find the one I really wanted. Yes, that is a crank sensor. You need that, and you need something for it to read. Yes, I have put a magnum in front of a stick trans, but in a car. With the truck transmission, I think you can use a factory Ram truck flywheel. You will want to verify that yourself, as I have never done it. Whatever you end up doing, you’ll need to cut a hole in your bellhousing for the crank sensor to live in. I did a video series called The Three Pedal solution where I cover a lot of what you will need to do - but again, there will be differences in your case.

[@gliddenschristmaslightshow4410]

good day again, I have done some research that you might be able to help with. I don't have the spare parts lying around to test this. The magnum standard flywheel has the spots machined into it for the crank sensor. It typically comes with a 12 inch clutch. The 77 trans and truck comes with a 11 inch clutch but has a different size and spine to the trans, so I would have to use the 77s / 11 inch clutch to fit the trans. so will the 11 inch clutch bolt to the 01s 12 inch flywheel, I think the pressure plate might be big enough but I don't have parts here to try this. now lets assume they don't match, can a normal drill, drill a flywheel to except the 11 inch clutch. I don't have the means to turn the flywheel down like you did. I also wonder if that larger flywheel fit inside the bell housing.

[@MidnightOilsRestoration]

Hey Jamie, I have a couple questions about doing one of these swaps. Around the time you drove through on your trip to Tony’s (5/25) my town got hit by a tornado late that night. First time ever for a direct hit here and it really messed things up big time; the same storm jumped over to Arkansas within an hour or so and tore the area near Ed’s machine shop who Joe always uses too by the way…definitely a scary experience! It picked up a 383 off of my porch which is around 3 feet high and set the motor about 6 feet away on the ground! It didn’t roll it over or tear the covering off-sat it down in the exact same upright position…unreal🤦🏻‍♂️! Well, one of the big trees came down on top of my 97’ Dodge Ram 4x4 crushing the extended cab in the process. That just made the 5.9 a perfect candidate to put into my 76’ B200 shorty van😁. 🤷🏻‍♂️gotta look at the bright side right? So, my question is this.. are there any issues using the transmission from a 4x4 like mine? Since my truck is a 97’ itself (when a lot of changes seemed to be happening), is there anything that I should look for to identify whether mine was before or after the changes? This will be my first actual magnum swap into a classic. My van was needing the wiring harness redone anyway so this should be tons of fun 😅. Hopefully when I get it all lined out-Tim from (318-will run)will be freed up enough for a visitor….ya know in the spirit of your crusade…maybe I could line it up against his black van😁that would be cool. Any suggestions you have on the switch out would be greatly appreciated, thanks in advance brother.

[@DeadDodgeGarage]

Wow. Well that’s unfortunate, but I like where this is going. Haha. On the transmission, that’s a bit of an issue. The 4x4 transmission has a transfer case adapter that is not easily removed or swapped for a standard tail housing. It requires a replacement output shaft as well as the housing, and complete disassembly to change it. I believe for ‘97 that will be an electronically controlled 46RE. That wouldn’t be the end of the world since you already have the computer and wiring to control it. The way to tell them apart is by the electrical connector. Rearward of the shifter and kickdown linkage connections on the driver side, you will find an electrical plug pointing straight up. It will either be an oval plug with three wires, or a round plug with 10 or so wires. The latter is found on the RE computer controlled transmission. Armed with that information, you can start shopping for a RWD transmission that matches your donor, and your swap could be that much easier. If using an RE, what you really want is the 97-98 version of that transmission, because it still has an old school speedometer drive that you will need if you want your van’s speedo to work. Anyway, hopefully that helps. You may well have seen it already but I’ve got a whole playlist on other Magnum stuff that I’m sure will come in handy for this operation. Good luck.

Found this video just in time. I have a '92 dakota with the 5.2 magnum and the obd1 pcm has finally died. Those computer modules are next to impossible to find. Very few available from parts pullers and none with any kind of return available. No aftermarket support either. Shipping outside US almost doubles the price. So, correct me if I'm wrong. I can change to a later obdII pcm if I use the wiring harness that goes with module. My transmission is the 46RH so I dont need any transmission hookups. As far as I can tell none of the other vehicle functions are integrated with the pcm. It appears that the ideal unit would be from a '96 Ram pickup, as those still had the hydraulic shifted transmission.

[@DeadDodgeGarage]

Yes. Exactly that. It’s a pretty easy conversion to make, and with ‘96 (and I think ‘97?) the engine connectors are still the same. Any newer and you’ll have to change the intake, crank sensor, and distributor - and you’ll have a bunch of transmission codes.

Sounds like you lost an accessory feed. This could be a blown accessory feed fuse or an ignition switch failure - among other possibilities.

Ok, this is an interesting point I chose not to take the time to cover in the video for some reason. Ok, that reason may be that I had totally forgotten. Anyway, my stick shift Charger with Magnum 5.9 would stall when it went into fuel cut and coasted to a stop. It just wouldn’t recover when you clutched in. If you blipped the throttle once while you were slowing down, it would come out of it and not stall. Weirdly, our van with an almost identical drivetrain does not do that. I believe the van has a ‘96 stick computer and the Charger has an auto computer. I was pretty sure this was related to not having a VSS. So it’s not 100%, but some computers will do that without a VSS reading - apparently.

I’ve made the notch with a cutoff or grinder wheel. Not too big a deal, but it helps to have the later transmission to measure for reference. You won’t be able to use the kickdown rod. The throttle body is turned 180 degrees and uses a long throttle cable and kickdown cable to reach it. You can easily adapt the kickdown cable to work on your ‘91 transmission.

[@DeadDodgeGarage]

Use your original oil pressure switch and wiring and leave the newer switch out, or use a pipe tee and mount both. And for the coolant temp you can either use a tee to fit both, or drill and tap a second 1/8 pipe threaded hole to fit the original sensor in the front of intake near the thermostat. A ‘92-97 intake would have had two sensor holes, so there is a flat spot on the newer intake where it could be drilled.

At first I was thinking just changing the engine and put all the 318 stuff on the 5.9 but after watching this video and seeing just how simple it is I'm now thinking also going with a 46RE since the PCM controls it and just swap the entire unit and get the harness and PCM at the same time. Now, my question is, since I don't have any donor parts yet and can be selective with what I buy what years do I need to be looking for? Watching this leaves me to think that maybe a 2001 and up but I don't know how far or is there are any other differences. I see the Rams on MarketPlace all the time being parted out, I just need to know what would be best to watch for. Thanks for the info and I'll be watching some more of your videos, good stuff. DC

[@DeadDodgeGarage]

You want about a ‘98-01 1500 for your donor, or that can go up to 2002 in a 2500 or 3500. That would give you the RE transmission, as well as the compatible PCM, and the easiest wiring to adapt. Having a ‘90, you also have a fuel tank with a pump in it already, and the TBI wiring system in place that adapts to the Magnum system really, really easily. You will have to change the pump to a higher pressure, but that’s not a big deal at all.

[@dbc105]

@@DeadDodgeGarageThanks, that helps. Are these PCMs flashable/programable like the GM 411s? I'm thinking a few mods while I'm at it and will likely needd a little teaking afterwards.

[@danielesquivel9957]

Good afternoon, I'm a new subscriber and I really appreciate your videos. Though I have one question. I have a 1995 Dodge Ram 1500 with a 5.9 and I want to place it into a 1988 Ramcharger that has a 5.2 , would it be possible to remove the 1995 PCM and power distribution and place it into the 1988 Ramcharger? Is it compatible? Thanks!

[@DeadDodgeGarage]

I’m not sure that the power distribution box would be an easy swap over. I’ve never done that. But it’s pretty straightforward to use the PCM and engine harness and adapt them to the truck. I did essentially exactly that in our 1992 Dodge van, except I used 1998 wiring. And then of course you’ll need the later fuel pump in the tank.

[@disturbedchild666]

Thank you! Quick question that I may have just missed but is you fuse and relay center in conjunction with or instead of the original fuse box?

[@DeadDodgeGarage]

I don’t use the original fuse box at all. If you are using Durango type wiring, you would basically have to. I just add individual fuses and relays. Simple.

[@rh752]

Thanks Jamie. Any insights into wiring for crate motor small block swaps? I’m guessing it’s a lot simpler

[@DeadDodgeGarage]

Oh, so, so much simpler. I guess I could do a guide on that.

[@rh752]

Info on mopar crate swaps is pretty thin- I found a bit but it’s all over the place. Most crate motors seem to be of the 360 magnum variant- Most confusing has been sorting external to internal balance flywheels, and wiring.

[@DeadDodgeGarage]

@@rh752 have you seen my 318 to 360 swap guide from two Sundays ago? I cover the balance difference, the mount difference, and other various details you’ll need to watch out for.

[@RomanMelnyk-nj8ux]

But if you chop the harness from the box to the cab you should Only need battery power key power ona few wires correct ?

[@DeadDodgeGarage]

Yes. Good luck figuring out which ones they are though. You’ll need a truck harness diagram, or a whole bunch of time tracing it all down. And there are so many more wires there than you could ever use. What a headache. I’m guessing you are the person who commented the same thing elsewhere, and I answered there as well. In my view, it’s way too much work to adapt that box, when it contains way more circuits than could possibly be necessary in a classic swap, and it’s big and ugly. There are much better options available.

[@lifeonadime4703]

Man such GREAT info in this video 👌. I do have a quick question though. Would the engine harness and pcm be the same between the same year (say 99) 5.9 gas between a 1500 and 2500? I'm about to swap a 5.2 or 5.9 into my 98 v6 5 speed ram and I'd really like the donor to have manual trans wiring so I don't have to deal with the auto junk. It's much easier to find a manual 3/4 ton than a half ton in my bone yards. Thanks for the awesome info!

[@DeadDodgeGarage]

As far as I know, they are the same. And if they aren’t the same, they’re probably still same enough to run.

You said something about the pcm not being happy if you don’t have the 46RE hooked up? I have a nv4500 in my truck already, is there something I need to do if I’m using an automatic harness?

[@DeadDodgeGarage]

Just changing the PCM or having it reprogrammed would do it. You’ll have a bunch of transmission codes. Not a real issue - but it may behave oddly in some situations, like slowing down coming to a stop.

[@DeadDodgeGarage]

I don’t think the skim key would be a problem yet in ‘99, but I’m pretty sure those harnesses are different? I don’t know nearly enough about the 4.0 Jeep harnesses, PCMs, etc. I just know that they are functionally pretty similar to Magnums.

[@ytelpeloncito5151]

I want to 318 swap a 1988 comanche. Im getting a 1998 durango for the donor, whats the best harness for the swap its a 1988 jeep renix, would a ZJ harness work better than a ram ?

[@DeadDodgeGarage]

The Durango harness is very similar and would probably work fine. The problem with either option is the hard wired dash section. You’re going to have to cut almost all of that out and adapt the rest if you want to use the fuse and relay box. You’ll have to change headlight connectors and lots and lots of other things to make it work. This is why I prefer to just use the engine harness - and why the Ram is the best donor.

[@silver_cd]

I have a question. Are these 97 and older PCM’s VIN programmed or too old for that? I have found a 5.9 with the wiring for $50 but it doesn’t appear to have the PCM.

[@richarddavis5542]

Wow. I was thinking about a Magnum swap for my 67 Charger - it is an original 318 car. I was wondering if you gave up on the 44 or 46RE transmission? Did you have to wire in an overdrive lockout? I was wondering how hard the shift linkage conversion would be since my Charger has a console shift. Thanks for all the info.

[@DeadDodgeGarage]

Shift linkage lines right up, kind of. In my car, instead of modifying the floor or crossmember, I moved the drivetrain forward and notched the transmission. So I made an extended lower link, and a custom bracket to brace the bottom of the console linkage. And believe me when I say, it worked *very* well - but the transmission was bad when I got it, and I knew that. Eventually, second gear left the building. So that was a problem. If you check out my series “The Three Pedal Solution,” I discuss all of this in the first episode or two, and show everything that I did to make it work - as I’m ripping it all out… if I had used an actually good transmission, I might still have the damn car. It was so nice to cruise. You do not have to have an overdrive cancel button unless you want to. It will shift into OD, and drop out for kicking down and passing or going up hills. Usually you’d only need the button to turn OD off for towing, and of course my Charger wasn’t doing any towing. But it’s not too hard to add if you want it.

[@DeadDodgeGarage]

I don’t know about about computer pinout and sensor connector differences between the 4.0 and Magnum setups. In a 3.9 V6 truck, you can add the extra injector connectors, swap the PCM and you’re good to go. You’re not going to have the same luck coming from a 4.0… but it really isn’t all that different. There is a way to do this that results in a sanitary swap. But I can’t tell you every little connection you’re going to have to make to accomplish that. It will involve partially de-pinning both PCM harnesses, stripping both engine compartment harnesses, swapping things around, re-wrapping…

[@codyduncan1760]

Do you think i can just use the durango harness that already had everything integrated (same as the 4.0) and just wire the jeep headlights etc into the durango harness/computer,

[@DeadDodgeGarage]

@@codyduncan1760 Yes, you absolutely can do that. People have done the same thing for classics, simply adapting the headlight wires and such to connectors that fit their lights. Just a good bit of work to get all of that stuff routed, trimmed, and up and running.

Hi Jamie, does it matter if the harness is from a 4x4? In your opinion is it even worth running the 46re in a classic?

Doesn’t matter, and… it depends. Those transmissions are always blown up and don’t fit well. But I had one in my ‘66 Charger briefly, and it really cruised great on the highway. But then it blew up.

What cold air intake is that also was wondering if you knew how to fix a p0207 and a p0208 code

[@DeadDodgeGarage]

P0207 and P0208 are injector circuit codes for cylinders 7 and 8. This isn’t like a V6 to V8 swap or something, is it? Haha. I would inspect the wiring for those injectors. If nothing is found, I would resistance test those injectors and compare what you find to one of the others. You could have two bad injectors, but that would be odd. I have no idea what cold air that was. Looked cheap.

@@BradleyBurgett then I wouldn’t bother changing the other injector. Open up your wiring harness and look for booboos…

[@mopar6586]

Yes it matters what way you hook up the trigger wires on the relay as a relay will make spike fly voltage. That being said most automotive relays have a diode in them to stop the fly voltage spike! 85 is ground…. 86 is positive…. If you are using a relay that doesn’t have a way to stop fly voltage you need to get one that does as the fly voltage can damage a computer and other electronic equipment.

No bus indicates communication error on CCD bus between the PCM and gauge cluster. Did you swap the PCM? The ‘97 PCM does not support CCD.

You can. I find fitting that big ugly box under the hood of a classic goes against my taste, and removing all of the donor truck’s wiring that is unused and then routing new circuits to it is much more work than adding two or three relays and fuses separately. But that is definitely an option.

By completely ignoring it because it doesn’t matter. Lol. Before the advent of chip key security, the VIN is programmed but it doesn’t really mean much for our purposes. The important part is which engine it’s programmed for. I have swapped these back and forth in swapped vehicles with no issue. It could potentially be an issue for communication between various modules (gauges, body, ABS, etc.) in some factory applications. But obviously that’s not what we’re doing here.
