Help identifying these wires
 

Hey I'm almost finished wiring up my 71 c10. The posted wiring diagrams on here are super helpful, but I can seem to find this set of wires and how they connect.
Unfortunately while I was pushing my truck around the driveway I ran over this set and can figure out how it fits in the schematic.
Thanks so muchfor any help.

I have a home for all the wires according to the wiring diagram, I'm just scratching my head where these plug in

Without a better picture I would say it's the AC harness or the TCS harness (transmission controlled spark) an emissions system that most guys rip out because it does nothing much for performance or emissions.

Here is a diagram of the AC wiring for you to examine. The power wire plugs into the fuse panel CIG terminal it's orange, and the AC switch has the colors shown.
There is a green wire that goes to the AC pressure switch and a purple wire that goes to the blower motor.



Attachment 1809365

The TCS harness is mostly on the engine firewall with a couple of relays and a plug that goes down to the transmission and one that goes to the carburetor'

Thanks vette vet.

I dont see any purple wires in this set. I figured they might be something along the lines of what you mentioned.
Heres a few close pics of the wires.
Thanks again.

On my 70 gmc 4x4 one of these switches is mounted on the firewall. I cant tell whats going in and out, as the wiring is a bit of a mess on this truck from P.O.
(No AC on both trucks)
