Tom Mc Posted July 31, 2025 Report Posted July 31, 2025 My M20C has an external AUX Power receptacle on the cowl just below the battery. It has been disconnected. By the batter is a solenoid that also has no wires to it. I have looked through my wiring schematics for this installation- not to be found. Does anyone have a M20C aux power wiring diagram and parts? Having an AUX power input would help me solve my other electrical / comms issues... thanks

Does anyone have a M20C aux power wiring diagram and parts? Your’s is a ‘62C? The auxiliary power plug wasn’t on the C until ‘69, I think? Here’s a screenshot from Man 106, with a link to the downloads section. It’s probably going to take some digging through the manual to see if what you have is what came from the factory. There’s versions for C & G models and different versions for the E & F models. Maybe the only difference is due to the battery location? Was there any reference in the logbooks as how your AUX plug came to be installed? That might give you some info as to what version you have. 1
