Hi,
I just replace a new motor to the Heater blower box. I know the connector wire consist of four wires, the main power, and 3 control, but where the ground wire. Did I miss anything? Billy |

The heater fan is in the engine bay and has only two wires. I think you are referring to the fresh air fan under the cowl? If so the ground is through the fresh air fan relay.
Check the schematics for your model year here: https://bowlsby.net/914/WiringHarnesses/#ReferenceLibrary |

Mine is a 1975 914. I’m still a bit confused. I’m looking at the entire assembly, and it appears to be all plastic. How is it grounded? Regards, Billy |
