Sorry, I was blowing 20A fuses. I now have a 20A circuit breaker jury-rigged in its place. I will try to figure out wire size tonight. I assume you mean the red and green wires to the motor pump.

I currently have interior out, and left kick panel is pulled out of the way (too hard to fully remove).

Does someone have a pic of their circuit breaker on the firewall?

Also, 69 wiring diagram that I have does not have convertible circuit anywhere I can see.
