LSx Swap Harness How To Simple & Free DIY Standalone on the Test Stand

Showing the cheapest, fastest and easiest way to setup your LSx harness in your swap project. Detailed video of how to make the stock unmodified LS truck harness work by just giving it power in two spots. This method is simple, free and gets the engine running, but it sure isn't pretty.
People often ask me how I run the LS motors without modifying the factory harness so I make this quick list of what I do:
- First make sure that the VATS (Vehicle Anit Theft System) is disabled in the PCM by having a tuner turn it off when he "Flashes" the PCM. (You may want him to turn off your emissions at the same time.)
- Give power to the main fuse block terminal post.
- Then give power to pin A9 of the C1 plug of the fuse block. This will be you ignition hot. Thats it.
- Make sure that you've given the fuel rail about 58 PSI of fuel and it'll run.
I control the starter with a seperate switch or you can just jump the solenoid.

To have your VATS disabled from your PCM or to just buy another PCM already flashed the way that you want it, "CoolMike222" on eBay sells this service cheap and I know that he's a good trustworthy guy from previous transactions and interactions with him.
Here's a link for example.

The link below from LT1swap.com shows you a photo to help you find where to give power.

Now, that's just one example. It's the cheapest, fastest and easiest setup, but also the ugliest setup. To accomplish other harness methods for a cleaner less cluttered looking install, you must not be afraid of reading a wiring diagram. Once you look at it and see where I've told you to give power to, then you can follow that to know where to give power if you chose to run without the stock fuse block.

=============================
Q&A from the comments under this video:
Q: Can this be done with a drive by wire throttle body and harness?
A: Sure, I'd bet it's near the same. The main difference will be that you'll need to have the pedal and its harness connected as well, when running it. Also if interested, you can easily convert a DBW to DBC by adding the IAC and TPS pigtails to the harness and have the PMC flashed for DBC when you have the VATS removed.
Q: If I bring all the wires with harness like you did with fuse box will the trans still work also?
A: Yes
Q: Can I put this setup in my project just like this and everything will work and drive fine.
A: Yes, but there will likely be other wires that you'll want to hook up. One example is the TCC wire.
Q: What about the OBDII port?
A: If you'd like to use the OBDII port, you only have to find the one OBDII signal wire in the wiring diagram and run it and a power and ground wire to your OBDII port and it'll work.

So I commented a few months ago asking questions about a 5.3 complete with wiring harness and I planned on swapping it into my c10. I saw the video and got bored, so brought the engine to my apartment house at school. Started it in my driveway after a buddy with HP tuners pulled out the VATS for me. Had a spare walbro hanging around and it did the trick. Just need to find a trans that will work and the swap will start!

[@mcqueenfanman]

Put a shut off valve right where the air goes in on that canister, it'll run quite a while on it. I've done that to move cars around that have dead fuel pumps. I usually set the pressure a little low so the regulator doesn't open.

[@AGearHead4Life]

Good idea

thanks. I did know about the brake pedal for the converter release. I found the fuel pump relay wire and managed to wire all that today. I had the 52 Chevy running today for 20 minutes. Tomorrow will move to the Plymouth coupe...again thanks

Yep!

[@morgansword]

Maybe I can't wrench anymore but I still have fun watching. Double D put a LS in a fifty seven more door n then converted it to a tudor. He made that part easy cause he did one and learned and I ask myself why we didn't do that when kids as two anything was high an more doors were tow aways. Even better, he used pontiac doors on a chevy with no grief. It was his first LS swap and nervous as a long tailed cat in a living room full of rocking chairs. He couldn't of googled it as he bought wiring looms and had a mess going and also wiring is not his strong suit. Now no problem, grab and throw it in. I watch another channel cause he builds rat rods as they have probably had the longest run of project cars. I think the next thing is building subframes that let you do a direct bolt in and power steering is right there. Long and short, his buddy grabbed the mess and tied it together like you and then the magic of touch the jumper in this app, and it fired right up in front of him. The look of shock took facial to the dumb bear look/LOL. I never had all this fun but fixed a few cars for my own use... I wrenched on heavy equipment and made good money cause for me that was it. No computers, or facebook or google, it was the fifties and even the "cell phone" had a cord on it for ship to shore at three or more a minute.Don't get me wrong, I loved the fifties and on up to early eighties still not much in way of a computer.. some small attempts but nothing a bone head like me to worry about as the ground outs or open circuits were easy. Guy I worked for got a new drill rig and took the keys out making it hard for me to service so I hot wired it then after making sure everything was coatsure went and hid it behind some other stuff.You could hear him blowing and I asked him what was the problem an he told me that someone had stole his hundred tho drill rig so I kinda wound him more said ya I seen it moving and thought you came back.. Finally couldn't take it anymore as the guys heartsick told him where it was parked and he tells me not to tease him right now so quick hot wire and drive it back out in sight. See, I am a mechanic an he is just making it hard on me... he got over it slowly and came around

[@jojow241]

Never knew it was that simple, everybody makes it seem like it's extra hard to do. Thanks AGearHead4life

[@AGearHead4Life]

jojow241 NP man! Most make it sound more difficult because they believe that you have to strip it all the way down to individual wires. You only have to do that if you want to complete customize your harness. I usually don't have much time, but want it to look a little better than it does with this bulky fuse block. So I take it one step further than in this video. I cut the plug off that goes into the fuse block from the harness and use a smaller universal fuse block to give power to the same wires that had power from the fuse block. It's basically just all the pink wires.

[@AGearHead4Life]

No. The pump makes the pressure. So it has to go before the regulator. Regulator regulates the pressure and returns the rest to the tank. It's tank, pump, regulator and then to the rail.

[@AGearHead4Life]

+Christopher Ryan Thanks Chris! If you unscrewed the engine harness from the fuse block, you got enough. You may want the fuse block too, to make it run like i did in this video, but you can always find that in a junk yard. OBDII ports can be found in any vehicle after 1996. So just cut one out. They're easy to wire in, just need one signal wire, one power and one ground going to it.

+AGearhead4Life Hi Mark, I was going to try to fire mine up today and I'm curious if I should take the water pump off to fire it on the engine stand.

+dawan antonio No problem! Those custom harness will look a lot better though. If you decide get get one that's cleaned up, I know a guy that is much cheaper than $750. I believe he'll redo an old one for closer to $300. Check out "LS Wiring Harness Conversions" on facebook. Good guy.

All this info helped me a lot with my LS swap. Running the factory fuse box. Pretty much the fuel pump wire and the ignition wire..going into my 86 k20 followed by MrWhitels1

[@AGearHead4Life]

Awesome Fan! Glad to hear it. Thank you for sharing your feedback.

[@agentnugent1021]

Simple and straight to the point....all I need now is to get an engine 😂

[@bryantmatthews93]

This is why we love the ls engine

[@ianw5920]

I am currently ls swapping my truck this helped me out a lot thank you and you just earned a like and a new subscriber

If you tire of those horrible engine stand casters there are plenty of much larger ones out there. I even converted on engine stand for outdoor use with two rear spindles and wheels off a front wheel drive VW Rabbit and extended the "tongue" as a tow bar. I put my engine hoists on car tires on the rear and solid farm equipment wheels up front. I can pull a big block in a sand yard and everything is much easier to push and pull.

Battery time doesn't matter how long it'll run, if you're running without water the bearings seize up before the battery dies. Friction= stuck valves, stuck lifters, spun bearings, etc... The computer has no way of knowing how hot it is the sensors usually reading water temp not ambient air. But I see everybody firing them up, I guess these later style engines are designed to put up with a bit more abuse. Great video by the way, as always thank you for sharing man.

[@AGearHead4Life]

craigr13666 Thanks Craig! Yea, you're right. They'd probably seize up before the battery would die with no water and overheating. The friction that your describing would have to come from excessive heat of no coolant, because it's got plenty of oil circulation.The computer does have a very inaccurate reading of the engines temp but it's a lot closer than if it was unplugged. The heat transfer through the head will bring it closer to 130* by the time I turn it off. With the sender unplugged, it would assume that it was -38*. But that doesn't really matter so much because that will only change the fuel delivered. It's not going to help cool since they're no fans. These motors do handle a lot of abuse, but I don't see running them for 30 seconds with no coolant causing any issue. BUT I am known to take risks... often. lol The only issue that I've been concerned about is possible hot spots from not having the water there to dissipate and move the heat. But I feel safe about it. I haven't had an issue yet and if I do, I'm sure I'll post a video up about it.This motor possibly has a bad head gasket. I found milk in the pan once I got it home. The seller said the motor ran great, but had gotten rain in it from having no oil cap. So, I plan to test the head gaskets once I have the radiator hooked up. It'll be nice to have coolant circulating, get the motor to operating temp and be able to test the motor better before it goes into the car. Besides that, it's fun and motivating to watch.

hanks for all the video's...I like the power Wgeels in the back ground,, I build them for my grandson who's 4!!

[@AGearHead4Life]

+Tom Park Thanks Tom! Yea, the Power Wheels can easily be gear head fun, for sure.

[@lilsadboy69]

I’ll never forget that pin now 😂😂 thanks bro

[@nuclearbum9858]

i have a 93 suburban and im trying to decide on going back oldschool 350 build or doing this ...dont even know where to start with a ls swap but i love the idea of this way

[@AGearHead4Life]

CONCRETE MONEY LS would be a much better route, but the choice will be your decision. You’ll have to decide if you’re ready to figure it out and make it happen. Good luck on the decision making brotha! Keep on Wrenchin!

[@mikemataria7741]

I like this guy he makes it simple not complicated 👍

[@AGearHead4Life]

Thank you Mike!

[@aabbelectricproductions2932]

[@AGearHead4Life]

+Dakota H Awesome Dakota! Glad to hear it man.

[@gilbertcordova3105]

Your bad ass, ive been watching your videos as you make them.Your really getting me more inspired and comfortable to this swap.

[@AGearHead4Life]

+Gilbert Cordova Awesome Gilbert! Thank you for your feedback and support.

[@MrMSA90]

And you got the video done before all that rain came in to haha good job on explaining all this!!!

[@AGearHead4Life]

MrMSA90 haha Thanks man! and you're right. I finished shooting right before it rained. It was sprinkling as I moved the engine back into the garage.

[@keithphillips1234]

Finally a video with full details!! I got a 86 swb c10 im really wanting to do this and use my 700r4. i hope this doesnt cost a fortune..

[@Alan197730]

Awesome job my friend, and it will clean up nicely once you peal all the wires away, because there is, like you said only two real wires to power it, and the rest are O2, map, tps, sensors and so on, and so on. Anyway thanks for sharing, and keep up the awesome work.

[@AGearHead4Life]

+Chevy King Thanks Chevy King! Will Do!

[@Alan197730]

No prob.
