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?

To Jeff's point, heater blower fan is in the engine bay with two wires, orange and green on a 75. Those two wires have connectors that go to the harness by the relay board.
