bought this gps because the car model didn't quite cut it on the bike. gf was holding it and somehow? we always made a wrong turn or missed the turn, DUH! now i'm looking in my service manual and i can't find the orange/white-black wires marked 29B on the wiring diagrams. any help here BEFORE i tear into this will be greatly appreciated. i took out the air temp gauge and put in the oil temp on the ultra here if that is any help towards steering me in the right direction. thanks, kev.
