[VintageLambo] Window motor 4 wire to 2 wire

Okay, I tested it out tonite and all is copacetic. I rushed the schematic, but it"s correct electrically. The unladen current draw is about 1.8 amps, laden draw is 3.6 amps with the motor I have from a Fiat 131 Brava. The current protector cuts out at 6 amps at about 2 sec, so it"s going to work fine. There are 4 wires in the door, three from the switch console, and one to the door ground through the current protector. Just move the current protector from the ground location in series with the window motor wire, either side. Tie the black lead at the switch console to the blue lead which is hot all the time. My diagram shows two wires horizontally across the top, just use the one black wire and jump to the relays in the door. This provides +12V source to drive the window. The blue goes to the wiper of the switch and picks either the up or down relays via the white and brown leads to the door. Piece of pie. No guarantees expressed or implied, your mileage (wire color) may vary. Keep your 4-wire motors, I"ve heard that the Maserati club will pay plenty for them for old QP and Ghibli cars, he-he-he. Doc
