Interior Wiring Harness Question

Machlovin · Sep 12, 2012

Does anybody know what this 'tied off' connector is for? My MACH 1 has some loose ends in terms of interior wiring, so I bought a used wiring harness so that I can replace what is missing. However, this connector seems to serve no purpose on this wiring harness as well. Could it be for air conditioning, or another option?

There are a few more plugs that I need to identify, but I'd start with this one. I have wiring diagrams, however I could not find this one on the diagram.

Thank you!

Which connector are you referring to?

The one at the very bottom that is taped down. Mine had tape on it too, so it appears to have been done at the factory.

I believe those lines are for the key buzzer reminder, the parking brake warning light, and the front marker lamp signal (which presumably tells the buzzer to buzz when the key is off and headlights are on). They are not required to actually run the car.

That makes sense. My sport lamps flash when I signal, but not my marker lights.

One more question:

The plugs I am holding in the picture below have nothing connected to them in my '71 Mach 1 harness (in my car), however this '73 harness has a buzzer connected to one plug (regular buzzer, this harness has two of them) and two small black connectors that have nothing attached as well.

In the wiring diagram it states that these plugs were only used after 1971. I'm just wondering if that is the case, then what, if anything, was supposed to be plugged into the small black plugs in the '73 harness pictured?
