Fiat Dino Forum (FDF)

I have purchased a new window motor for my 1967 Dino coupe from Superformance. It came with one red and one black wire.

The old motor that has failed has 4 wires, so I am at a loss as to how to wire the new motor into the car.

Can someone point me in the right direction?

Thanks!

This subject has been discussed before. Search the Forum for "Wiring electrical window" from June, 2020.
If you want the keep your original window switches, you have to include a polarity change relay - like the relay
shown below - one for each side:

At the original switches, use only no 2, 5 and 4 connectors. No 1 should not be used, so disconnect completely.

Connect the blue wire (FWD) to no 2, the black wire (0V) to no 5 and the the green wire (REV) to no 4.
The original + 12V power wire, connected to no 5 (grigio/rosso or azurro), should be connected to V+ connector
at the relay, and 0V connector should be connected to the ground (chassis).
M1 and M2 are the power feed connections for the window motor.

I came across this diagram when I had to replace a 4 wire motor with a new 2 wire motor. It works but if you are replacing with a 3 terminal switch, the lower diagram works well.
