72 Dart Blukhead Disconnect

[APK]

In the engine compartment of my 1972 Dodge Dart there are two wires not plugged into anything coming out of the bulkhead disconnect.

First plug is a single Dark Blue wire coming out of position "M" of the bulkhead (see attached image).

Second plug has two black wires taped in with others but looks like they are coming out of positon "L" and "N" of the blukhead. (see attached image).

For reference there is a single yellow wire coming out of position "P" and a Dark Blue with white tracer coming out of position "M".

I tested the plugs with a volt meter and they are only "hot" when the ignition key is turned on.

I have a wiring diagram but not sure if I am reading it right or where it is taking me.

Does anyone have any idea where these are suppose to plug into?

Thanks for your assistance.

Wiring diagram is your savior, here

You can download a 72 service manual here:

or go to "My Mopar" and get "alternative" diagrams

M is not dark blue but black, is the brake light warning circuit

L is dark green, feeds the horns

N is dark blue, is your "ignition run" circuit, and feeds the alternator field, the regulator, the ignition system, electric choke if used


P is large no12 black and is the output from the alternator

Does this car run, or a project? Someone has chopped things up

I have the 1972 Dodge Chassis Service Manual. The car runs great. The only thing so far that I have found that does not work is the radio, the warning buzzer if the headlights are left on, and the idiot light for seat belts on the dash. Don't know about the break light warning circuit. The Power Steering and Power Brakes were added, not factory. Hear are few photos I hope will help.
