Item:    45-1896    Add-On   (in stock)

This is an isolated trailer wiring harness. This is made by Add-On and is designed to isolate the wiring between the bike and the trailer to prevent electrical feedback into the bike. 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 battery. It has four relays that are activated by the factory wiring harness. This plug and play harness will fit on all 2012-2017 Goldwing GL1800's. This will NOT fit the 2001-2010 models. Installation instructions are included. 45-1896
