This winter I plan to build a trailer to pull behind the bike. I have also added a trunk with lights in it. I decided to add a Hoppy converter to change the 5-wire bike system to 4-wire for the trunk and trailer. I purchased it at KMT Parts along with a 6-conductor trailer connector.
I installed the Hoppy converter in the trunk. When I tow the trailer I'll unspool the wire to connect the trailer. The rest of the time the wire will be hidden. I'll be adding some LED lights to the trunk which will connect at the terminal strip.
The whole mess is hidden under the trunk insert's preformed pockets.
I ran the wiring harness under the chrome fender trim.
The harness connects under the seat. I added the terminal strip during my cruise control installation.
