Standalone LS Swap Harness: If I Can Do It, You Can Do It

Thanks for making this video. The wiring is the biggest thing keeping me from pulling the trigger on a swap for my 1970 C20. Your video makes me think that I can do this.

[@scottlavoie2363]

Hey man you can run the stock harness. On those trucks just power the fuse block with the grey connecter A9 run that to your factory 70 truck ignition wire(distributor power wire) and then70s starter wire to LS, fuel pump comes out of that as well, run your lines with pump in tanks or inline pump out of tank. Done!

[@dapetik]

​@@scottlavoie2363 I would imagine it would be nearly as easy on an 80 mustang? I'm debating buying an eBay hundred-dollar stand-alone harness. I don't really have the time to fiddle with the ls 6 harness I have now

Great video and content. I might have simply taped the connectors and would remove and save for a later ( to be unfinished LOL) project. Most of the GM style weather-tight connectors use those and the factory (prolly in Mexico) did a better job of making those than I might

[@centralscrutinizer76]

I got a 4.3 , the harness and pcm came with the motor and was cut in pieces , i rewired it with wire I bought off ebay . After a couple or months the motor wouldn`t start , i had been using the wire on other projects ,they were failing too . The cheap ebay wire the copper conductor turned to green dust not just the connections ,but the entire length of the wire .

[@troyfitzpatrick7672]

Looking to do a stand alone for a 4.3 vortec going in a Luv where to find a print out of what wires I can get ride of that I don’t need. Thanks Troy

[@shrekdaklown]

if you havnt found your answer yet just use a v8 pinout only difference is number of injectors or painless sells a stand alone harness at least i know they did

[@socalob]

Was your harness that clean when you pulled it off or did you wash it? If you did what did you wash it with? My truck harness is full of grease, oil and a ton of dirt. Not to mention the wires feel as if they are stuck together lol. Great video, I really appreciate it!

[@aaronpage1822]

I would like to know the same thing.

[@DillonTurner395]

This part was a cake walk, the challenge for me is figuring out how to get the engine in the car. Nothing around here but dirt and mud. engine hoist dont roll well on dirt or in mud. having a concrete slab installed isnt an option either. Tried to use friends garages and stuff but you know how that goes so here I sit, with a 5.3 ready to go into an s10 with no way to actually get it in there.

[@shaneriley6384]

Dirt driveway myself ! Get some heavy plywood and put some sheet metal on it so the cherry picker doesn't crack through . It rolls pretty good .

[@swaggass20]

[@shaneriley6384]

We used 3 tree's chained up and a come along to do these jobs. thick 4x8 Plywood on the ground where the hydraulic jack holds the tranny. But that's life in the Woods. But Good luck 😁

[@Jamestfarrell]

So, I understand that this harness mod makes it possible for the LS engine to be dropped into, say, a bare-bones 1949 Studebaker truck which has been converted to 12V Negative ground? Help me out here!

[@williamdon3442]

I got a 98 GMC Sierra I plan on having it awhile. It’s older yes but if I can over come my fear the dreaded wiring harness a 6.0/4l80e would be my first major upgrade to modernization. Thank you for the video sir it was very helpful

[@LoganCheatham]

What do you mean by a stand a line harness and with the wires you terminated from the fur box, what do you do with them? And after doing this process do you just plug the pins in to the ecu and clip on all the parts to the engine and trans?

[@flatnastyproductions5810]

Standalone harness means you can run the motor on a stand, or anywhere outside of a vehicle. Thats the best way to describe it lol

[@Thuli_KB]

@@flatnastyproductions5810 what a good explanation. i will never forget it. thanks for sharing your skills. cheers

[@Z28Batman]

Great video. Excellent information. If I'm using a 2004 harness but putting drive by cable throttle body on, how should I do the pinout? I would assume I would strip the harness as if it is the 99- 02. Thanks!

[@ReinGeyer]

Did you ever get your answer? I'm doin the same thing

[@ReinGeyer]

Also, do we need a dbc pcm?

[@p.b.sHUNTING]

What state are you in? I’m in SC and just purchased a 96 s10 2.2/5spd for my son and I to tinker with. I have a complete drivetrain/harness/computer from a 96 full-size (5.7/4l60e) but I’d rather have manual trans in the s10. I have no problem with the mechanical side but the electrical blows my mind.

[@MrJackson66]

Did you ever finish the "stand alone harness" ? To be a stand alone harness it needs a fuse box and some relays hooked up... Its a nice start .

[@ragtop67firebird]

Thanks for doing the video's. Very helpful.

[@JohnDoe-fz9ck]

Can i ask doing a harness for an electronic trans..would you leave all trans pins in the connectors?

[@LidZLife]

@@JohnDoe-fz9ck Yes I would do it that way. With mine I'm doing a 5.3 and 4l60E into a 1984 Regal.

[@enriquemedina5769]

Great job you master I was do this on one connector it was to much money I was decide to rebuild by my self it was an hit

[@beardedgaming1337]

im not clear on what we are doing here. a donor engine with its factory harness and you are repining it to plug into an aftermarket control ECM or?

[@pedrito376]

[@randalljames1]

Have you done anything to retain the "Flex fuel" system? (white 56 PCM wire) ?

[@jah2029]

What do you do with the wires that were left with tape at the end? I got lost. Lol

[@dougessany4830]

I agree. The video was very nice and helpful but I was confused at the end on what your going to do with all the wires you cut out and taped up. Any info would be appreciated

[@Rayvisin]

The cut ends are deleted or integrated in the cars dash harness for low oil light, cel, etc

[@garagedadtalk6251]

This is a good video. We are swapping a 68 with a LS1. We may take this route and give this a shot. Wish us luck... Not alot of electrical wiring experience. Thanks for the Vid!!!

[@edgarza4649]

Well explained thank you for sharing

[@winstonclyde]

Whats the purpose of de-pinning the harness. Why cant you leave the wires in? I really dont know, not being smart

[@Brooklyn_Powers]

On my KA swap that I did, I left the harness with everything on it and just wired/hooked up what I needed. It was my first swap so I didn't want to screw anything up by removing something I shouldn't...I ran it like that for 2 years, with plugs not plugging into anything, etc...I recently pulled the harness out and removed every wire/plug I wasn't using: It cleaned up the engine bay nicely! So you can leave them in, however, it just looks so much better without any extraneous wires or plugs.

[@sarblade]

If I may ask, when you rewrapped the harness, what tape did you use? I don't want to use electrical tape, but the OEM stuff. Do you know what that stuff is? Thanks. Great job by the way

Say Iam swapping a f body or whatever and I have a lq4 and want to do manual swap . Can I use a t-56 trans and use a T-56 harness from a ls1 f body along with the front end accessories?

[@fuzzymoto896]

Yes. you can use a t56. you can get a t56 harness or if you have the auto harness just use it. You can tuck away or remove the wires for the auto trans. Harness is the same, just a few more wires and plugs to run auto. Ecm does not know the difference. Depending on year of ecm you may want to have some CEC removed on ecm if you go stick on auto ecm but engine will run fine either way.

[@mnice59]

I might be treating this like a redit page but honestly what did he do here? He referenced the web page that told him to remove these wires but I dont get why. I incorrectly thought he was going to create a NEW wiring harness with new (non brittle) wire.Its obvious that if he was putting it in a same vehicle hed need the same wires so I assume its other than that. How would this website know he didnt need these wires?

[@TheRealMisterChopShop]

Great job

[@thehellbird8946]

I'm installing a 5.3 into a 99 but I cant figure out how I am going to make it work. I cant find a cheap LS1 harness from a trans am or camaro so I might have to improvise with the stock 5.3 harness. But shit on the 5.3 harness is not in the same location. I'm using the stock truck injectors and fuel rails. I just dont know how I can make a stand alone work from a 5.3 truck harness. If I was to find a 5.7 harness everything should plug and play accept the truck fuel injectors. Those will have to be spliced to the ls1 harness. It's a headache

[@mckreations5160]

You can get jumper for injector harness to go from one to the other without having to splice and easier, just cost. As for location of items, most things for a stock 5.3 a close and just require a little lengthening or fore thought to change their location from. One brach harness to the one closer to its position for your application... unless I'm not understanding your issue

[@shrekdaklown]

the truck harness is even easier and with a 99 you can easily intigrate it into your trucks harness for your obd2 port and gauges

[@thehellbird8946]

Already got it covered. Ended up using a harness for the F-body. Got all LS1 fbody accessories. Everything's swapped over. The build is 98% done. Just hooking up hoses and lines. Little stuff then put the exhaust on. It a wasn't cheap build that's for sure lol
