GL1500 ISO Trailer Wiring Harness

This is an isolated trailer wiring harness. It is designed to isolate the wiring between the bike and the trailer to prevent electrical feedback into the bike. It also reduces the chance of overloading the bikes taillight circuits. This is a 5 wire harness. If you are using a trailer with a 4 wire system, you will also need to purchase a 5 to 4 converter. This 5 wire harness gets the power for the trailer lights directly from the bike battery. It has four relays that are activated by the bikes factory wiring harness. This plug and play harness comes with complete instructions and will fit on all Goldwing GL1500's from 1988-2000.
