Safely and effectively apply the load from your trailer lighting to the battery and not to the rest of the bike's electrical system. Eliminate blown fuses caused by overloading stock lighting or accessory circuits. Our relay harness utilizes inputs from the motorcycle to direct power from the battery to the appropriate trailer lighting circuit.
5 Wire Plus 1: Our kits provide standard 5 wire output (run, brake, left turn, right turn, ground) plus a bonus wire that can be connected as needed to provide fused 12v power to the trailer for compartment lights or keyless entry systems that are wired independently of the trailers essential lighting.
5 to 4 Wire Converter: Plugs in & allows our Wiring & Relay Kits to power trailers requiring a 4-wire harness (run, left turn/brake, right turn/brake, ground). The bonus wire is still available to provide fused 12v power to the trailer for compartment lights or keyless entry systems that are wired independently of the trailers essential lighting. (Includes 4-pin flat vehicle connector)
Receptacle Kits are not included because the style of receptacle required varies by trailer manufacturer.
