Can’t find any info on wiring diagram for the 46-48 Mercury 4 wire heater motor.
Should be same as the Fords in that era. Think it’s an Eaton. Mounting in my 46 Ford. Any help appreciated

My '48 heater switch only has two terminals. Fresh air type heater. I've never found one of these for sale or a wiring diagram to show routing. Red goes to battery and other to heater fan? Can anyone 'splain this?
