Need help again...

The pink wire on mine I believe was the ignition wire to the coil.

The car ran fine without this pink wire being connected to anything so I am not sure if it's has to do with the coil...

The pink wire should go to the brake warning light. This light will illuminate when the parking brake lever is pulled, or when the brake pressure shuttle valve is "activated". This pink wire is hot, as the circuit is completed via grounding through the parking brake switch or the brake pressure switch. There should be a gray wire that also attaches to the bulb.

How about the seat belt warning buzzer relay in the upper left of your pic? Your wire colors don't show in the wiring diagram, but it appears to be the only place left.

When I took the dash off, those wires were hung very close to the buzzer. But from the electronic schematics, the buzzer is connected with a single wire on each prong and not paired one like these so I am a little unsure. Also, is this buzzer in the correct location, attached to this grounding stud?

I wish you were right but according to my first pic, shown with the green arrows below, I already have the pink and the gray wire connected to that warning bulb. The pink wire that I need to know about is also bigger.

The schematics are not always accurate. They show that there should be two gray wires connected to that bulb, and you clearly have only one gray wire.

I still suspect that those paired wires connect to the buzzer relay shown in your pic. Was the buzzer working?

As for the larger pink wire, there should be a pink wire feeding the headlight switch that is always hot. Is that one account for?

John

I my wiring diagram I've only found two pink wires that are hot all the time. One is input to the ignition key, the other is input to the light switch.

My diagram shows that they come from fuses 7 and 8, then meets up into one black wire, and later separates into two pink again. Probably doesn't make sense. But I hope the top paragraph helps you.

Mikael,

Yes, it makes sense. There is a red wire that goes from the battery positive post directly to the ammeter. On the other ammeter terminal (the "load" side), there is a black wire that goes to the alternator stud that is marked "BAT". There are two places along this black wire where four pink wires are tapped (spliced). One tap has two pink wires that go to the headlight switch and the ignition switch (terminal block). The other tap has two pink wires that go to fuses 7 and 8.

In summary, the load side of the ammeter feeds everything except the starter and the "A+" terminal of the voltage regulator.

John

The pink wires for ignition block and switch are both accounted for. I finally realized that this actually is violet in color and NOT pink and found out it lead to fuse #8. From the schematic shown below, it seems a live wire was added to the dash that have no functionality. I'm confused even more...

Me too. I have diagrams for all years, all the newer show a Violet ending in nothing. The older diagram has a Violet going to 65 Direction Indicator Switch. But it's only Hot when ignition is on.

There are also a few always hot Violet wires in the interior light system, where the door jamb contacts create ground. Most Violets go to Interior Light Rocker Switch

Now that we know the color, it appears that you will have a spare hot-all-the-time wire.

I have noticed that the wiring diagram at Pantera Place for the "early L Model" may be incorrect, as it is the same as the wiring diagram that I have for my 71. Mike??

John

While searching around to figure out the wiring, I noticed that there is a tab on my ignition key block (shown below). Can someone reassure me that it's suppose to be like that or am I missing some kind of wiring there too. Thank you.

Mine had a separate home made looking wire to ground, to one of the bolts holding the steering column. I THINK it's there to make the key warning buzzer work. It's annoying, and most people take it off to get rid of the noise, but I'm old school, everything has to work, so mine works.

My car is about the same age (#2548, a pre-L '72) and in about the same state of disassembly. I'll see if I can find the same wires in mine. Rod.

Mine is #2332, so we are not far apart. Please let me know. Thanks

OK - just got my dash out & found the two pair of wires in your first photo. They are bundled together with the wires for the speedo and the brake warning light(s) between the pods. In my car, the red/blk & blu/wht pair, also the red & grey pair, are folded back and taped off; they don't go anywhere. This appears to be as original.

I did notice on the schematic are shown two warning lights between the pods, and I have seen some cars that have two. Mine, and I assume yours, has only one. The mystery wires however don't match the schematic as shown for the other warning light. I don't know what these wires might have been intended for. Maybe I'll see something when I get it further apart.

I haven't yet found the large pink wire with the bare terminal on it, I'll look again next chance I get. As for the ground lug on the ignition switch, I believe Mikael is right. Mine has it too, and it was unused.

Rod,

I feel much better now, at least we have something in common. Is your buzzer mounted like mine? Let me know where your other relays are too, when you get to them. I can't seem to find mine yet, may be I need to pull more of the carpet off.
