hey guys. i got a new wireing harness out of a junk truck and wired up the engine bay, but the truck i got the motor harness out of the under dash was all cut up and junk. there is a saburban right next to it that has a good dash and good under dash harness but it is a tbi model and my truck is a carbed model. so my question is will the harness for under the dash be the same for both trucks or do i need to fine one out of a truck like what i have? my truck also has the power windows and stuff so idk if that effects anything.

thanks, Dalton

You can uae the harness from the TBI truck, you just have to cap off the wires for the ecm and fuel pump. I suggest keeping them installed incase you decide to use them for an add on in the future. Any fuse block should have a place to plug in your windows and locks. My truck came without them and i just installed a factory set up and it plugged in and worked fine.

I mentioned before to cap the wires, but pulling the fuses will yeild the same result. the point is to not have live wires floating around
