This is for an 81 but it should be pretty close for a 79

First thing you might check is the "Interior light delay timer", remove that from the circuit and see it thats the problem.

My 79 also had a drain on battery. I removed all the alarm wires and it will sit all winter and still start. I believe it was the wires you are talking about.

I had this a few years back. Turned out to be a bad alternator.
