Thanks, this is the best c10 wiring explained That I have come across. Now to find a great vid explaining wiring my relay box which is exactly like yours

[@MohawkMotors]

Glad you were able to get some good information out of it! I actually am working on another swap that I'll be using the same relay panel and will do a more in depth explanation on it when I get to that point. Thanks for watching and commenting!

Thanks, Guy🦾🙏🏽

[@MohawkMotors]

No problem!

[@papergatorzfedducca7998]

Wish you would’ve showed the relay wiring . I’m new to relays. Still a good video and one of my favorite channels.🔥🔥🔥

Hey Jason Great video I have watched it about 12-15 times now. Lol I still have been able to get my square body running. It’s a 88 suburban Silverado. And in my hick head has only 2 large red wires. And a bunch of extra wires Anyways I still can seem to get mine running I have the aftermarket 4 wire fuse box Fuel pump comes on I get fuel to the rail but not pumping I was hoping u could help me please

[@MohawkMotors]

Hey Peter, so you have fuel pressure at the rail but the pump doesn't run when the key is on? Am I understanding correctly? Are you using the pcm to control the fuel pump or just a simple relay controlled by the ignition switch?

[@Cucvfreek]

Im really close to wiring my cucv for its ls swap. Good info i might message you if i have more questions.

[@MohawkMotors]

That's awesome, yeah feel free to reach out if you could use some help!

[@mattjones2722]

Where did you get the aftermarket relay box?

[@noahlenert466]

So how do you wire it if it doesn’t have the third power wire

[@MohawkMotors]

You could run your own power wire, or tap into another circuit, or split one of the circuits you used already.

[@gerardolopez5875]

And what did u did to the other wires? The ones u mentioned on the block, the grey/blue,a/c wires, yellow,etc????

[@MohawkMotors]

The ones that I didn't use I just put heat shrink over the end to seal it and coiled them up in case I need them later.

[@gerardolopez5875]

@@MohawkMotors @ purple wire from truck? Goes direct to starter???

[@BUILTBYBLAKE424]

You running the stock 2 pin neutral safety I take it ? considering your using purple wire to excited ? Or did you by pass the safety switch ?

[@MohawkMotors]

I just de-activated the neutral safety in the PCM.

[@bubbabatterby7059]

What harness wise do I need to keep from the squarebody.

[@MohawkMotors]

I didn't keep much of the engine harness, just a couple of the wires powered when the key is on and the starter excited wire.

[@bubbabatterby7059]

Thanks man. How about inside cab harness.

[@MohawkMotors]

Left it alone, all I did inside the cab was add my boost and AFR Gauges

[@bubbabatterby7059]

@@MohawkMotors yeah I was wondering because the computer that's above the heater box.

[@colbylange9282]

@@bubbabatterby7059 if you're LS swapping, you can get rid of that lil computer or just disconnect and leave it. It was used for the distributor timing.

[@DMD81773]

All of those relays and fuses for the injectors are not necessary. Injectors are fired one at a time. Not all 8 at once. I had a 15 amp fuse for bank one and another fuse for bank 2.

[@MohawkMotors]

Good to know, will save me a little wiring and space in the panel for the next swap!

[@JohnSmith-qj4cf]

I bought the holley terminator max x dbw im now poor this con version is not cheap

[@MohawkMotors]

Nice! I want to do a terminator at some point, right now I'm not doing anything wild enough that the stock computer can't handle it and I can't justify the cost of terminator until I actually need it. I think everybody's definition of cheap is different, but I do believe that they can be done for under $1000 if the person is willing to take the time to find good deals, and learn how to do what is needed.

[@JohnSmith-qj4cf]

@@MohawkMotors my othe conversion i used howell good

[@pmotorsports8276]

Since you're doing fuel injection. Why not have the computer control your fuel pump?

[@MohawkMotors]

To be honest... I ran out of relays and I wanted to get it started asap. I have a few changes I want to make now that I've had it driving for a few months, and getting the fuel pump wired to be controlled by the PCM is on that list of changes.
