Identify a few wires, with pictures. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hopefully this is pretty simple.
The three wires on the right. Light brown, brown/white, thin green. The second pic is of the plugs that go with those wires. Anyone know where they go. I know one is for the little switch on the master cylinder. What about the others?

Final wire is a very thick green wire. Not the light green one on top, the dark green near the bottom. Its the wire on the left and that is the plug. I was guessing that was the horn..?..?

I "think" The tan might be the brake switch connection for the proportioning valve and the small green is the temp sender.

I think the heavy green is the horn. Send me your email and I can send you a nice color diagram

tan/white= prop valve
green 14 ga. wire is temp sender in dr. cyl head.
green 12 ga. wire is for the horn.
I think that the one for black/ white should be for an ammeter.

Its brown/white. Its not the ammeter because i have accounted for those two already. Thats the only one i cant seem to figure where it goes...

You have the connector 180° out of how it fits into the firewall connector, but here are some pics. of how mine goes. Seems like it is part of the TCS system

In that location, mine starts out as brown, then breaks out of the main engine harness and becomes brown/white up on top of the cowl

Large green seems to be horns, but didn't look real close at that

That wire wasn't in the diagram but my Jimmy also has that wire. Mine was not hooked to anything?
