65amp wiring/trouble shooting
When the optional alternator or heated back light was installed, another set of wires was added and the standard wires cut, removed or left in place. We don't know what the factory workers actually did.
Standard battery circuit connection at the starter relay is just sires A1A and A1B
For your car, A1E and A1F were added.
A1B was left in place even though it wasn't going to be used.
Now lets see if we can explain the other wires on the starter relay.
When the key is all the way in the start position, power is available in wire S1.
Inside the relay, this connects with wire S4. If the safety switch on the transmission is closed, the circuit will be complete.
Current flows through the key switch and activates the starter relay.
When the relay is activated, the battery junction gets connected to the terminal below it with wire S5.
Wire S5 goes to the solenoid connection on the starter. The solenoid activates and connects the heavy cable on the starter to the starter windings. Starter is now powered.
This leaves "Brown 2" wire.
Exactly. Thats what I meant in the question about standard versus optional.
Chrysler had a standard harness.
