LS Swap for Dummies - Wiring made simple - Prepping a LS Motor for your Old Hot Rod

[@DDSpeedShop]

Hey guys! This is my first attempt at a factory harness LS swap so go easy on me. Leave a comment and subscribe to the channel!

[@GNF-bf1bo]

Can't go wrong lt1 .com it's gonna be cool old truck.

[@Brandon_obs_ls]

Why did u want oem instead of something like terminator x I have been wanting to use oem also but just wondering why u chose oem. Also ur right why take apart the harness just to take out wires just leave in in

[@Jaydoubleu83]

Limited space, time, and budget. I'm sure a lot of us can relate to that! Working on a rusty old truck in a small garage is about as real as it gets!

[@DDSpeedShop]

haha yeah its not scripted

[@2thehook773]

Love how you do everything yourself. True hotrodder!

haha cant wait around for help, nothing would get done

that's the only way to do it is yourself and if you don't know how to you learn how to first then you tackle it

I have watched a few videos and they make it seem much harder. Thank you for dumbing it down for people like me.

[@OldGrumpsGarage]

good progress brother. Thanks for demystifying the whole LS Swap scenario. It's been a running thing in some circles that you had to buy a controller and harness, etc spending thousands of dollars to make it all work. This is fantastic stuff!!

[@DDSpeedShop]

so far its just talk haha. i hope to back it up in the next few videos

[@jimdandy2275]

Wow. Just today I was thinking of this truck swap. I think it is the first videos of yours I ever saw. Been following along ever since. 👍

[@johnyesko9006]

Dan, I think you would like Jonathan W. He fixes old cars. There is a ton of knowledge, ingenuity and engineering that is there for the taking. He is cool like you.

thanks buddy, ill check him out

cool project , I'm almost 60 years old and just now thinking about these ls projects , been a mechanic my whole life and have never done this, always did everything old school way with a small block , I'm watching and learning !thanks for your videos .

You're right the LS wiring looks intimidating but it's pretty simple. I've done 2. First one I used the factory truck fusebox and all. The second I used the fuse block set up shown on lt1swap.com. the second looks a lot cleaner. Like you I didn't pull out all the unused wires. I just couldn't see the point in it. They don't hurt anything being nipped off in the factory harness and I think it looks good. Keep the good videos coming. Another good video is from gearhead4life. He shows the bare minimum to make an LS run on a stand. It's what pushed me to start my first swap

[@DDSpeedShop]

Yeah it's so easy now that I see how it all works haha. Thanks for watching!

[@vintagetintrader1062]

I like your simple explainable style for video, no crap on and on over useless info as so many do, I came for a quick look as I do plan one of these swaps on day.

[@DDSpeedShop]

sweet! yeah no point going on for a simple project

[@macharleys72]

Great stuff man, the way you make it simple is inspiring to a lot of us that would be normally scared to tackle an LS swap....Thx for takin us along...

[@DDSpeedShop]

No problem. Thanks for watching!

[@cw2lido]

I had to remove four broken exhaust header bolts on a LS4 using an easy out. I broke the bit on the first bolt, said some choice words and felt defeated. Got the drill out and drilled the easy out bit out and some of the exhaust bolt, used a bigger easy out and thank God it worked! I would say your method is the best method. Thanks for the wiring lesson, you are a LS wiring Professor!

haha take it with a grain of salt, im no expert haha

[@ibraunchy2462]

Looking good , Dan , Short story: No offense meant , When i was younger was under a car with a lit torch in one hand and a hammer in the other , a little bit of rolling around on the creeper and my hair got wrapped around a creeper wheel , luckily i killed the torch before flaming the car and rolled off the creeper , drug creeper and myself to work bench and cut about 6 inches of hair off , went into house and grabbed my beard trimmer , removed the depth gauge, stepped out on back porch and buzzed it all off , As punishment it now refuses to grow at all

You have yourself a sweet channel my friend. You're like everyone of my buddies and makes for great content. My buddy has that same truck but has the choked out 305. Hoping this build helps push him towards the LS swap. We been on him for years now to do it. And same exact rust issues in the same spots. Friggin New England winters destroy everything that hit the roads

[@DDSpeedShop]

yeah they all rust in the same ways, atleast the metal is kinda cheap

[@Nova.1971]

That was very informing on the LS wiring......But a real pain in that small spot to install. Well done once again!!!

[@jefferymaclean9467]

Hey Danny. Just wanted to say, been watching since the start of the 57,and I know what it is that I like about your videos vs other KZbinrs videos. It's that you cut out the BS and stuff that maybe people just don't need to see and cut back in and explain what was just done. In my opinion much better than playing music and forwarding the Videos and can't see what was done anyhow. Just my opinion. But again I like it. Keep it up Friend. Edit: yes I know you forward as well but very little.

[@LeeSmith-BigK51984]

After seeing you break down the hole wireing thing it don't look to bad.. You actually did a good job explaining it.. But to me if I was gonna go that far in to that many wires I would just rewire the hole truck there's cheap kits out there anymore.. So if your gonna add that many to the stock fuse panel.. You might be better off. Looking into a aftermarket harness and just rewire the hole truck.. I would rather be safe than sorry.. Seen too many great cars and trucks burn over bad wireing.. Great job getting that motor IN there also.. Another great job.. Like always.. Keep the wrenches a Turin and the tires a burin.. And keep up the great work..

Didn't you say you cut the O2's out?

[@HalfassKustoms]

The rear o2s where cut out still using the front ones.

[@mikesonneson2824]

Pink has been a common GM ignition color for many many years. You kept saying saying key on for this color wire. What you should tell your viewers who are learning by your video, the pink wires are true ignition. Meaning the key energizes this wire and it stays at 12 volts through the crank cycle. The accessory circuit of old days was 12 volts when key on but would lose 12 volts when the starter was engaged. Good video.

[@thecollectoronthecorner7061]

Ive learned its much easier to just remove the entire front cap. Well worth the bit of work to remove it.

[@DDSpeedShop]

yeah keep it simple haha

[@79tazman]

If you use antiseize on the manifold bolts they are easy to get out next time without breaking or having a hard time getting them out actually it's a good rule to antiseize any steel bolt going into aluminum because they like to weld each other sometimes in place it makes it much easier to remove next time.

[@DDSpeedShop]

yeah your probably right haha

Does it through the blanco off on the crank to elongate the holes on the flex plate.

[@thequadsquad4801]

The 4l80 flex plate works best no spacer needed and torque converter bolts right up

[@monkeywrenchization]

One thing I learned doing these swaps is to remove the Intake manifold, and inspect the wells where the detonation sensors go. Many times they are filled with water, and the sensors are badly corroded. Replace both sensors, and the wiring, throw out the foam blocks, and build a dam with RTV. easier to do now, than later on down the road. On later models, the sensors were moved to the side of block..

[@DDSpeedShop]

thanks buddy, good to know

[@monkeywrenchization]

@@DDSpeedShop This is another lesson I learned, remove and clean the fuel rails, injectors, and so forth. I couldn't get my engine to fire because only one injector was working. I took the fuel system apart, what a terrible odor, it made me sick. If you ever smelled old gas, you know what I'm talking about. I found that it is easier to replace the injectors. There are numbers on the side of the injectors, they tell you things like flow rate and lbs. Lt1 swap.com has the information.

[@joeschlotthauer840]

So, is the fix for the exhaust manifold bolts, just different and better bolts like ARP. I guess I'm asking your viewers if there is a known "fix"...

[@chuckelliott258]

Anti seize after getting the broke ones out
