I've spent the last 4 hours trying to sort through the wiring mess behind the center gauge panel of my '68. When I pulled the panel, maybe a third of the wires were hooked up. The rest have been hacked and spliced (in hilariously poor fashion...) and mostly painted yellow. I have the wiring diagram in the Haynes manual and the one papawana so generously sent and I think I've identified nearly everything. Below is what is left, which I've had no luck finding. My last hope is that someone will recognize the plugs and wires and be able to help.
Picture 1: Dark blue wire and what looks like pink. There's a third spot in the middle which doesn't have a terminal (but maybe it should??).

Picture 2: Pink/white and green going to this 90 degree connector.

Picture 3: One gray wire to the back. This one is to the right of the shifter and looks like it needs a long plug.

Any help you can provide would be much appreciated.

Pic 1 and 2 look like something added over the years.

 

Are you sure your car is a 68????

Someone changed your car to a later harness???

A buddy has a 74 and I looked at his doc rebuild wiring diagram as my 69 doesn't have any of those connectors.....

The first pic with blue and pink wires and one
Empty is a oil pressure gauge wire ???? which we all know 68 had a mechanical gauge.

Pic two is part of a seat belt warming system... That's the buzzer for a 72-77 seat belt alarm 2 yellow wires 2 yellow with black tracer wires.

Pic three appears to be the lamp connector to light the PRNDL on an auto shifter.

 

I think the grey wire goes to the cig lighter light....The power source for the cig lighter should be an orange wire. Can't help on the others.

Possibly. Nothing in the pics looks like stock 68 to me. UPC 12 in the 68 AIM has several pages showing stock wiring and a wiring diagram.

 

Thanks! I was coming to a similar conclusion. I have the 68 AIM, and went crazy looking for these. This wiring harness has so many splices and dead ends (with big sections of underhood wiring simply cut and hanging loose) I have no idea was the PO was trying. From what I can tell, it has duplicates of some things and some unnecessary plugs. Remnants of two separate alarm systems and a couple (apparently aborted) stereo installs. Still has mechanical tach and oil pressure gauge, but HEI distributor and, apparently, wiring for electric oil pressure gauge.
On the plus side, I now have all exterior lights working (including signals and headlights that raise and lower), working HVAC fan, and a working speedo. Still lack wipers (wires present inside, but none to be found under the hood...), horn (easy one), any interior lights (frustrating...), temp gauge, tach and oil pressure gauge. I verified good oil pressure, but the gauge is sticky. I found reference to clean-up instructions from Wilcox on another thread, but couldn't find the info on their site. I'll keep hunting.
Also, I put one wrong picture above. Instead of the buzzer as picture 2, I meant to put the below (which I still don't have identified).
Thanks again for the help!
