I was removing my clock and when I disconnected the plug, I accidentally pulled of the back half of the plug. I need to put the plug back together, but my wiring diagram is missing from my workshop manual.
My car is a '91 C2 Cab. I tried the '92 diagram, but some of the wire colors are different. Does anyone have a '91 instrument wiring diagram? A list of terminal numbers with wire colors would work. There are 14 terminals, 13 wres. (I believe #4 is not used) BTW, the new plexglass on the instruments looks great. Thanks for any help you can give.

Thanks, Bill. Is that for the '91? I see you have a '90. I have only 14 positions and 13 wires. I see your list has 15 pins and 14 wires. They must have changed in '91. Anyone else with a '91 diagram?

Wiring diagram attached. Make sure you get that trailer light hooked up right... wtf?? trailer light??

JD, Does that page specify it's for a '91 C2? It looks like the same one I have for a '92. The one I have is diagram 97-125 and is for a '92. I thought they may be the same, but colors differ. I need diagram 97-85. The wires are still in a circle, so if I can verify one wire and the empty pin, I think I'll be OK.Thanks

JD, I forgot I had a copy of the manual on my computer and it had the diagram. It was the one you sent me. The '91 and '92 were pretty much identical. Thanks for the help, unfortunately my wires are colored diferently, so I'm not sure what to do now. I'll look again tomorrow and try to figure it out.

The diagram was for a C4, but I would not expect that to explain the difference. Odd.

Here's Wiring Diagram 97-85. Sorry, looks the same. The title is "911 Carrera 2/4 Model 91 Sheet 6 Instruments and Sender".

OK, thanks to all who responded, I just figured out what I had wrong. First, I wrote down the light numbers instead of the pin numbers...DUH...I've had a very long day and shouldn't have started this project. Next, when I couldn't find the schematic, I called for help. Then I superimposed green for gray when I wrote down the colors... I thought there weren't enough wires until I stopped long enough to study the diagram. It seems I wouldn't need pin 8 (the missing white and gray wire)for the tiptronic since mine is a 5 speed. After leaving it for a while, coming back and reading the schematic completely, it made sense. Releasing the cable strap to get the wires out in the open also helped. Thank you to all of you, you were all correct. I guess I get the bonehead award tonight! I'm amazed at how fast you came to my rescue, you guys are great!
PS. While I was looking into the dash, I saw that the foam around the A/C vents is deteriorated. I guess that will be my next project.
