Need wiring help!

[oldchevyguy]

Hi Guys!

Been a while since my last post. Had to put the project on the back burner for a while to move. Im now in Bushnell Florida. Im doing the wiring now, in fact, for several weeks now. I am using a Its a Snap wiring harness because I had it laying around. Interfacing with the corvette column and the 06 GTO (LS2) engine has been a challenge.
At this time , I have two questions. ONE, Pin letter Z on the multifunction switch plug, orange in color. The manual says it goes to orange 959, a painless number which, if my research is right, means headlight battery +. My harness is designed for an older GM, and doesn't have that circuit. Would this be switched power for the turn signals a hazard lights?

Two, Fuel pump/ gauge wiring. I can figure out how to wire the pump, but the gauge has got me confused. My corvette fuel tank harness has 2 wires that go the a duel resister on the float. I cant find a resistance reading between these two wires and ground, but get a reading between the two. How do you wire this up? My LED gauge cluster requires only one wire.

Thanks for any help you can give me. Need to finish the car before summer!

Pin Z on the multifunction switch plug is wired to #959 on the Painless Harness, which is constant +12V power through the 20Amp "Horn" fuse on the Painless panel. Any 20amp fused always-hot +12V should work fine. So not switched power, but constant power.

And FWIW, pins W, X and Z all get +12V constant power from the same source.

I'll let someone else chime in on your number 2.

Good luck!

On your fuel gauge, out of the 2 wires that go to the float, the blue wire will go to your gauge. The other wire (gray or black) will go to ground along with the fuel pump ground.
