Mystery Wire Connections
 
I am looking for some help in identifying where a couple of wire connectors go on my 1985 Chevy K10. The truck used to be my daily driver, but has been sitting in storage for the last 10 years, so i don't remember what doesn't work. The truck runs and drives fine, so i don't think it's anything super important. I think the big connector goes to one of the plastic plungers on the brake pedal bracket, maybe something to do with cruise control? And i have no clue about the green wire with red connector. Any help would be greatly appreciated.

Have you traced the wires back to where they come from? Might be able to get a better idea that way.

Not yet, that is tonight's job. Was hoping someone would recognize them.

So i traced the green wire with red plug tonight. It runs up into a relay on the left side of the steering column near the firewall. I believe it's just a relay for the 4 wheel drive system as the wires that light up the 4 wheel drive shifter and the dash light that comes on when engaged all come off this relay. So i'm thinking that the green wire with red plug is just a diagnostic connection? it has a slot on the back side like it clips into something out of the way, but i'm not sure where. Can anyone verify if i'm correct in my logic?

And the connector with Gray, Pink, Green and Blue wires from the first post goes into the main wiring harness, but i still can't find where it hooks up, even my wiring schematic isn't helpful.

All right i found this image while researching my wiring question. I know now the black plug has to do with the cruise control, but still not sure what its actually plugging into. Maybe i'm missing a relay or something.

All right, i think I've figured out the mystery, I believe the connector which the red arrow is pointing to is the wires from the turn signal/ cruise control stalk on the steering column. I'm going to double check when i get home tonight, but i'm semi sure. The cruise control is inoperable as all the engine bay parts are gone except the wiring, so it's not going to change anything on the truck, but at least i wont have random wires hanging down.

I went out and looked at mine. I found the little clear connector plugged into the the black one like the pic shows. The clear one is the turn signal stalk. The black connector, unfortunately I could not see where it lead too. It looks like it comes off the main dash harness and stops there on the steering column with the clear connector. The whole connection is clipped to the steering column. So without taking the air duct out, I can't get a better look at it.

Thanks for your help! Now i'm even more confident in my assumption.

And of course there are no wires running down from the turn signal stalk, which explains why the cruise control didn't work when i bought this truck, even before i removed all of the engine compartment parts.

Yes thats the connector for thw cruise control stalk. Plugs into a black spade looking connector coming from the stalk. Depending on your column you might be able to swap in a stalk and just plug it in.
