i need a wireing diagram for a 97 gmc pick up. 2wd rc sb looking for the one that goes through the firewall. in the middle of a 4.3l to ls1 swap and kinda need to know this stuff.

 

what wires are you needing to find.

 

the ones that go through the passenger side fire wall. i need to know how to interface them back with the new harness.

 

You ever get any info on this? I could use it my self

 

a little but not much. he got most off ls1trucks.com. he's went out of town so we haven't been doing much. i do know the fuel level control box thing is in the fire wall on the passenger side and some other odd ball stuff.
