i have an 04 fb. i am thinking about doing the remote garage mod and took the headlamp apart to see the wiring. anyone know what each wire is for? i havent bought a service manual yet but will soon. there is a white wire on the left, 2-yellow up top and 2-black on the right of the headlight connector.

 

IIRC, the blacks are for ground (duh!), the white wire is the low beam power and the yellow is high beam.

Easy way to confirm (with out a manual) is to use a volt meter.

 

i can see black grounded to the bottom of the light assembly, i should of mentioned that, thanks.
