I have an 2004 GL 1800 Champion 2 trike with factory installed hitch and 6 pin round trailer connector.
i do not see an isolator on the wiing for the trailer and am wondering, if it was necessary on a first gen GL1800 or is it only the newer generation bikes? Seems to me the tirke dealer should have installed the isolator if it was required.
Should I be taking the tike apart and rewiring the trailer harness to include an isolator or is there a way to put an isolator on the trailers wiring harnes to isolate it that way?
