RIVCO PRODUCTS Trailer Wiring Sub Harness — Black – 10-12, 14-24 Touring, 14-16, 19-24 CVO, 14-20 Trike, 14-17 Softail

This sub-harness plugs into the bike's stock wiring harness on one end and connects to the 5- to 4-wire converter or isolator on the other.

It eliminates the need to cut and splice the stock harness, preserving factory wiring and simplifying installation.

All sub-harnesses require two additional parts for a complete trailer wiring harness assembly: a 5- to 4-wire converter (PART #3902-0134) and a universal trailer wiring isolator (PART #3902-0119), both sold separately.

Designed for easy plug-and-play hookup; use the appropriate converter or isolator for your motorcycle model.
