Fresh air blower motor wiring question., 3 extra wires not connected to anything.

[Poohsan]

My blower motor has 3 extra wires come out of the left side (when looking at if from the front of the car). These wires are not connected to anything at this time.

Can someone tell me what they should connect to?

Note:
The blower motor is not turning on. I am in the process of trying to figure out if it is wired correctly (noting else in the car has been up to this point.).

It is a 1975.

Thanks,
Arron

What colors are the wires? These may be the three wires (white, white/yellow, and white/something else) that go from the blower motor to the ventilation control panel in the dash. They provide the ground for the motor (through some resistance in two of the three cases) so the motor won't run without them plugged in.
