Found clipped wires. Where do they go? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Seems the P.O. decided to "install" his own anti theft devise in the 72 Burb. He left the keys in the ignition and decided to clip wires back by the distributor...

I found he clipped a green wire that appears to have run to the Oil sending unit. There was a yellow wire going to the + side of the coil that was clipped. The wire going from the - side of the coil to the distributor was clipped. Now, there is a black wire with a white stripe that is running across the top of the firewall that is clipped and appears to tie into the wrapped harness that comes out by the AC box. Also in that harness is a larger(12 ga.?) ORANGE wire that is clipped off. Coming out of the grommet where the oil pressure line goes through the firewall is another ORANGE wire that is thinner than the other orange wire(16 ga.?). What did these go to? I don't have a wiring diagram for this truck so if anyone has one and can send me a pic of it that would be great.

Again, this is for a 72' C20 Burb, 402, T400, A/C, with fact. guages.

Any help would be great! Trying to get it running before I yank the drivetrain...

Sounds like you have a mess!

Good luck, here is a link for the diagrams.
