Stop in for a cup of coffee

@slantsixdan and others have posted that Canadian built cars used direct drive starters and IIRC generators into 1966 model year. So I would not be surprised if the starter wiring was more like the 1960 A-bodies (eg Lancer) and if using a generator there may have been a current control circuit.

see for example
starter motor for slant six

Thanks. I'm going to pick up the trace on the inside of the bulkhead connector and see where it terminates. My guess is the ignition switch. There were a few other wired up items under the hood that I've since removed.
