Finish Wiring of a Stand Alone Harness

[ls1nova71]

Ok, I see. I didn't realize the first pic was a diagram of the harness you have. So basically you would wire it up like the second pic, at least the fuse block part, on the right side. Only difference would be you will only have 2 ignition fuses rather than the 3 in that pic. The other things will go to what ever they are for, MIL will go to the check engine light, TCC will go to the brake switch, etc.

I forgot to mention that I went and purchased the same Dorman fuse block and (2) 40 amp relays, plus the 8 pin connectors shown in my 1st post. I like the way it's clean and detailed...no loose wires, everything has a place, I like that idea.

Also I've been ordering wire (20g for the misc connections, 16g orange for the fuse block, 12g purple for the starter connection, 12g red for the battery to fuse block connection and 10g black for the ground from battery to body). I still need to get my battery cables and battery.

LS1, do you have an email that I could contact you regarding wiring questions?

hello 19SIKtySix. I hope all is well. i tried to hit you up on IG but you are private. from the pics i saw, doing the harness is pretty much cut and dry. oh, yeah, i've done this before. dm me your number and i call you to explain anything to help you out. Listen to LS1nova71, he's a god when it comes to LSx swaps. in a few of my own swaps, i put the stock harness, with no wires removed, on the engine and tranny, plug up a vats deleted pcm, wired my fuel pump, grounded the block, frame, engine, added 12v+ power/Ingniton and fire the motor up. of course i added fuel and connected the starter, but its easy.

Hey Dec010974, sorry about the IG thing, send me a request and we can connect on there.

As I've mentioned, I working with a modified harness already, I just need help with how to finalize the the fuses/relays and get this thing fired up. I feel confident in the seller's ability to modify harnesses. He sells swaps all the time and wires them this way on all of them, plus his personal vehicle.

Because of my lack of knowledge with anything auto electrical, I wouldn't know where to start. However, if there's a diagram or something visual that I can see, it'll help me tons.
