S4 headlight motor to replace an S5 passenger side
I had the passenger side headlight motor begin to operate very slowly on my newly acquired FC. Then last night it failed altogether. Fortunately I have a spare or 2.
The spare is off my S4, and when I pulled the motor, the passenger side S4 has relay on it. The S5 did not. I tried it with the relay and it didn't work. I checked for voltage at the headlight plug and I did have it. I pulled the relay out of it's socket on the S4 passenger side headlight motor to test it. it does get a signal.

So the plug with the relay connections sees this:
White w/red stripe - constant +
Black - Ground -
White - ground -
Green - Positve with headlights up
Now, I need to know which wires to jumper/connect to get the headlight to function safely. I assume the green wire must be jumpered to the black or white wires, but which one? Once I figure this out I can get my headlights working again.
