Hi Gordon :
I'm starting the wiring process and wonder where the three wires off a Ford FMS alternator go.
There is a stud with a red shoulder that looks like it should go to battery + ,the yellow,white and green I have no idea.
The yellow and green have flat spade plugs at the ends,if that helps.
Thanks,
Paul :confused:

Yellow goes to the stud with red plastic shoulders as well as the battery. The white and grey goes to the single pin connection next to the three wie plug. The green wire goes to the alt warning lamp with a 470 to 500 ohm resistor in parallel to the start swithc 12Volt....
