Since giving up on this thing I just tried to install it again. Still doesn't work.
I went straight off the brake light wires. I have a BLUE, a RED and a YELLOW/BLACK. (I know, different colors than what I previously thought!)
Anyway, I read some older posts that said "ONLY THE BLUE WIRE" so I did just that. Still...nothing. Suggestions? And is the "Original Back-Off Modulator" the right one for this bike? The modulator has just the two wires, a RED and a RED/WHITE.
