Big Bike PartsÂ® is known for its quality Plug â€˜N Go electronic trailer wire harnesses and the protection they afford. Their newest Electronically Isolated Trailer Wire Harness for the Can-Am Spyder RT is no different. This harness isolates the load between the motorcycle and trailer through the use of four fully automatic circuit breakers to prevent electrical feedback. The heavy duty circuit board can handle a continuous 16 amp steady load, with further protection provided with a separate 15 amp inline fuse from the power source. Easily plugs into the OEM Can-Am RT wire harness with no on bike splicing required. Works with 5-pin trailer connectors, not included.
