Finally got the 7 way connector working with my new TV.
Looked at access panel under front of my 1966
There is a completely rusted away breaker has blue wire on one side and a red and blue on other end.
I believe it is a charging breaker but do not know amp # to replace it with.
Next question below;
I now have working electric brakes...to my surprise. BUT...
The two blue wires at the rear access door are disconnected, I believe they are the breakaway break connections...If anyone has a pic of what the back panel should look like or where the two blue wires go I would appreciate it.
All the best,
