when i bought the car it had nothing.
i have the brown wire.
i have a 3 prong ns switch.
if i get an older backup switch where does the other wire go?
i have no wipermotor on yet, i have a 2 and 3 speed motors.
If you have a one-wire car and a three-wire transmission, just connect your brown wire to the center pin of the neutral safety switch. You can't just swap the switch with the one-wire one because the rooster comb inside the trans is different.
