Need help asap!

I'm in the middle of my conversion on my 96 c1500. Swapping in an 02 5.3. I'm using a Nelson stand alone harness. Here's where I'm stuck.

1. I need to know what wires in the c100 connector are for the temp, oil pressure, tach and speedo
2. Which wire in the c100 triggers the ac relay and does it use 12v or ground as signal

Last problem, I accidentally cut the harness going to the shift position indicator on the trans. I connected the wires back together, but it only works now when the ignition switch is in the first position (the first click after off) but not in the run position, any help would be great so I can get this thing done

Your last issue sounds like it is grounding out somewhere.

Anyone else correct me if im wrong but the signal for the AC goes through the GT100 connector over on the passenger side doesnt it?

i know it goes through the pass side connector, idk what number it is.

as for the other ones i have no idea its been too long since i hooked them up, grab ur good friend the tester and go to town on the wires. when the gauge moves there is ur signal wire
