LOL! I should have been more clear. I just wanted to take the Breakaway switch out of the equation, +12v source wire to the wire to the brake. 12v may show up in one of the wires??? I'm going to take my time testing and documenting.

I came back early from KOA San Diego. Great time, great for the kids. I only saw 3 AS, but the SOB trailers WOW! Amazing! ......back at it with the Argosy.

No, I do not have a power jack. From the diagrams, power for the jack comes from the TV and trailer battery wires. If one of those wires go to the jack...I need to find the other end. I was not able to locate the jack end of the wire. I will look again. It's my mission to figure this out this weekend.

It could be one of the house circuits. My 79 has a blue house circuit wire. Can't remember everything it powered but radio, a fan and a few lights came off it.

I believe I got it figured out.

1. My breakaway stays open. I need to replace it with a new one.
2. The (2)yellows in the picture. (1)7 pin harness and (1) to the brakes with wire nut connection.
3. Black in question goes to the breakaway switch. Tied now to the (2)yellows.
4. The blue is a mystery wire. Maybe to the power jack but i can not locate other end.

What really helped me out was the thread, Breakaway switch wiring.

TG Twinkie posted in there with his wisdom, detailed voltage readings for the breakaway switch and related wires.

Thanks to all who have replied.

TG twinkie if I ever have a chance to meet you, I would gladly buy you a drink. Thank you.
