Bestem undertail f4i ??
 

I just bought a Bestem undertail for my f4. Does anyone know what the wires are...(on the right light) one black, one red, one yellow, and one blue and (on the left light) one black, one red, one yellow, and one blue? Does someone have a diagram or something that I can go off of. A tutorial would be AWESOME!

How is the fit on the bestem?

i have a hotbodies under tail it worked out great awesome fitting.

just take them and test them...

on ur bike
green with a yellow sripe is brake
orange with green spots is 1 signal
blue with green spots is another signal
i dont remember what running light is
and green and with light green spots is your ground....

just touch the wires on ur undertail to the battery to test and see what they are...

remember ur black is typically your ground wire
