This is an electronically isolated trailer wiring harness. This is made by Show Chrome and is designed to isolate 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. This easily plugs into the OEM Can-Am RT or RT-S wire harness with no on bike splicing required. This is a 5 wire harness that gets the power for the trailer lights directly from the battery. This plug and play harness will fit on all 2010-2019 Can-Am Spyder RT's and RT-S's. 41-162
