Misc wires
Still trying to get my center console figured out. Does anyone recognize any of these wires? Are they used or left by the factory for future add on's? My entire interior was disassembled and in boxes when I got the car. Any direction would be greatly appreciated 
Thanks to all I am making progress. I found a copper ring does that go to clock? I have been told orange wire is cig lighter , blue and green wire is speaker. I noticed that there is a grey and a black wire that the ends have been cut off. There is a black and grey wire farther up towards the wire harness towards the dash. Does anyone think they go back together? There is just a few more to figure out and I can move on hooray

Hi Lr,
Do you have the wiring schematic from the Assembly Manual to refer to?
You can look for connectors with pairs of wires in those color combinations.
What area of the dash are the wires located…. left, center, right?
What's not hooked up yet?… 4-way flasher, turn signal flasher, courtesy lights, gauges, shifter light, cigarette light or lamp, a/c control lamp, speakers?????
Regards,
Alan

Orange wire with the white connector is for your cig lighter. Agree with Alan, look for the mate of each connector. I've had mine apart a number of times and have always been to reconnect base on finding the mate. Good luck

Blue/green is a speaker wire.
Think the yellow/purple wires are neutral safety switch.
I'm reaching here but I think the 2 black wires with that flat plug is seatbelt buzzer/warning lite.

you where right on about the seat belt plug in. If the Yellow purple wires are the neutral safety switch would they go down through the opening by the stick shifter to the trans? Again thanks for your help I really need it and appreciate it!!

GM provisioned harnesses with connectors for both manual and automatic safety switches. The one you're showing is for the NSS that mounts to the shift lever on an automatic. The actual switch for a manual car is mounted way high on the left side of the column support. The wires come out of the harness within 6 inches of the fuse block under the dash- same location for the rear body harness. Vendors sell a short jumper that connects the main harness pigtail to the clutch switch.

Ebay link for a pic.
The switch in the main pic is for the brakes. Look at the side pic that shows the "scizzors" type switch.....http://www.ebay.com/itm/1969-1982-CO...3D271845678316

Thanks I will go find that switch on my pedal. When I locate it is that where the yellow and purple one goes?

Single pink w/black strip with connector: Should have a mating connector coming from the rear defog switch. Unused if no rear defog.
Grey and black pair with non-factory (red) connectors: Unknown. Such is usually for a light that comes on with the headlights but there is no such in that location in '79. Perhaps someone added their own ashtray light as there was none in '79.
Black wire with large ring connector: cigar lighter ground
Brown wire with clear connector: Power blower fan (all speeds except high). You should find the mating connector coming from the fan switch.
Orange wire with clear connector: Power for cigar lighter
Grey and black pair with clipped ends: Shifter illumination. It's missing the twist in bulb holder like those used in the cluster.
Two black wires in black connector: Seat belt warning. It's mate comes out of the driver side seat belt latch.

Another possibility for that first grey and black pair of wires is that they are the original ground (black) and dial light power (grey) that led to the factory radio. That would explain the non-factory connectors.
If you hook up that amp you found under the seat be certain that you run a dedicated ground to a firm connection point on the chassis. Do NOT hook into ground in the existing harness! Why? It is filled with splices and barely adequate for the power it handles. When working on the cabin harness in my '79 (only stock accessories) every splice showed signs of overheating.

You're quite welcome.
