LS Swap wiring diagram
 

Hey fellas, so I've found a few different LS swaps available that are complete with motor trans and harness. The one I'm leaning towards has the flashed ECU, DBC, and set up for the "2 wire" I believe it's called. M

My question is if it is a literal 2 wire setup. We had a wiring harness installed from Qwik Wire a couple years ago, so it is all updated wiring. I'm just kinda wondering what is going to connect to what with a setup like that.

Its been a bit since I did my brother's wiring but it was three wires (four if you count the fuel pump).

1. Wire to the fuse block that was hot when key on.
2. Wire to the starter.
3. Ground.

I think that was it if I remember correctly.

Ok that's kinda what I assumed for the short harness. And then the rest of it is just the wires from the computer to the injectors and sensors etc. correct?

There's a guy I follow on IG who lives in Salinas that sells complete swaps with the 3 wire harness for a reasonable price. 99k to 115k miles on them, see them running. He's in your area Tiny!
