Can you identify these wires/circuits?

[nab407]

Hey guys,

I've torn out all of the wiring in my truck, bought the shop manual, and am currently in the process of identifying, cleaning, rerouting, and looming all of my wiring. However, and as to be expected, I have run into some wiring that I cannot identify even with the shop manual diagrams. Please help!

My truck is a 1983 Chevy K10, 4x4, Auto, w/6.2L Diesel

1) Out of slot #18 on the instrument panel connector, exits two pink wires. One leads to nowhere (the one in question) and the other is circuit 30 and leads to the main firewall connector. Circuit 30 is labeled "Fuel Gauge to Tank Unit"***

2) Again, from the instrument panel connector, exits a pink wire from slot #7. It currently leads nowhere. I don't know what circuit it is.

3) From the seatbelt buzzer on the main fusebox exits a black and white wire. Goes nowhere. Circuit unknown.

4) Three wires that were jerry-rigged to go to my cigarette lighter by the previous owner. Two orange, one white. I traced them back to their source and found that one orange goes to the horn relay, the other orange goes to the headlight on/off switch, and the white goes to the headlight on/off switch, as well. Circuits unknown.

5) Black wire sourced to factory splice with one end going to seatbelt buzzer and the other going to ground. Circuit unknown.

6) Gray wire going to "Instrument" panel fuse on main fusebox with a 5-amp fuse. Circuit 8A in diagram, 'Fused No.44 Circuit' on circuit identification sheet.

7) Yellow wire traced back to 'Radio' 15-amp fuse on main fusebox. I'm pretty confident this is the radio power feed, but I just wanted to double check.

Any help would be GREATLY appreciated and I'll give everyone $1000!



*Disclaimer: I will not give anyone $1000.

Thanks for the help. For 1 and 2, do I only need to hook one of them up to the sender then or should I splice them both together then run them to the sender?

3. I'm trying to bring the truck back to stock (as annoying as the buzzer can be), so does this wire just run to the seatbelt retractor?

4. No alarm that I know of...

6. Where do the grey and black wires lead?

For the sender use the proper hole spot. For the size you have.
I'll check but the buzzer is seperate in mine.
Grey is for the radio light, black is ground for radio.

Ok, so the black wire runs from the ground/seatbelt buzzer ground to the radio, as does the yellow wire, and the gray wire?
