We have sourced these top quality trailer wiring components from the Electrical Connection. The Trailer Isolation Relay Package is required for all applications. This harness safely and properly applies the load from the trailer lighting to the battery and not to the rest of the bike’s wiring/ relays/fuses. Subharness assemblies are required to complete the installation and are sold separately. A converter is also offered for those with 4-wire trailers wishing to use this 5-wire trailer Isolation Relay package.

NOTE: You must order both the Isolation Relay Package and the subharness. Receptacle kits are not included because the style of receptacle used on trailers varies from manufacturer to manufacturer.
