Hey guys, been a while since I have been on here, Life, kids, work and a slew of other things have kept me away from here. But I'll get to the point.

I am in the process if a GM LS swap in my car. I know there are those on here that don't agree with that, but it's my car, and I can always put it back.

I removed the entire engine harness when I sold my 302/t5 combo. I am am in the process of slimming down the dash harness and getting rod of the stuff that isn't needed (cruise, Airbag stuff, door chime). What I need to know is where do i find the wires for the following, and in what connector are they in.

Fuel pump power
Check engine light
Tach
Oil pressure
Water Temp
A/C (high pressure switch, and the clutch)
Charge light

My goal is to have as much of the factory gauges work (94-95 GT cluster, 93 GT body/dash harness, and a 2002 GM truck engine harness) as I can. I have the Dakpota digital SIG-5 speedo corrector to take my 4k pulse per mile VSS signal and translate it to my 8k PPM Speedo. Tach signal from the GM ECM is a 4cyl signal, and I can change that in the tune. For my Oil and water I am going to use ford senders in the respective locations, but need the wire locations to make it all work.

Thanks for the help!

Charlie
