In the 83, the only sensor is on the receiver/drier. Turns on aux. fan when a certain high side pressure is reached.

There must be a reason it is overheating. Just jumping the auxiliary fan to come on at all times is not the answer nor the cure. Find out what is really causing the overheating before you toast the motor for good. Check thermostat,fan clutch, plugged radiator etc...
Good Luck John

over heating
its over heating because that electric fan does not come on when
the ac is on.... and in stop and go traffic the main fan is rather slow.. if my fan clutch was bad would my fan be spinning on the engine.
