Trailer Module Issue

I posted earlier we took my wifes RTS to get C.B. installed {did not come in}and to have short to trailer module & reverse actuator looked at, It was repaired quickly ,module was BAD, grounded , no short in wiring found after seeing was a very basic plug and play almost no way to pinch wiring, thankfully dealer had another hitch to rob module from, they are still waiting on a blue trailer. Pulled the trailer the three hours back seems fine now.Note: even when module failed and blew fuse still had brake lights, no running or turn signals and assume trailer was not being recognized by bike,not issue bike is std. trans.Our best friend picked her new RTS Wed. an Auto. clutch elec. shift seems to be excellent clutch management ,very smooth shifting and perfect takeoffs,system seems flawless.
