This US-made trailer wiring kit powers the lights on a trailer while protecting your bike's wiring system and, on newer bikes, the engine control module. This trailer wiring kit fits Harley touring bikes from 2014 to present including the Electra Glide, Road Glide, Road King, Street Glide and Tri-Glide. If you have a 2014-15 CVO with a pair of AMBER turn signals on the rear fender, you want our CVO kit.

Choose either the 4-wire or 5-wire kit, depending on how your trailer lights are configured. If you aren't sure which you need, check out this video that explains the differences between the two systems.

FLHTCUTG Trailer Harness Review

Andrew on Mar 26th 2021

Harness looked great, shipped quick, and installed perfect. Worked like a champ and was very easy. Was a nice way to easily setup for a 5 wire trailer. I am sure that the 4 wire version would be just as easy and user friendly. Thanks.

Works like magic

The harness is a blessing and works awesome. I did have one issue but it was my issue with my aging eyes and little numbers on the wire labels. Once I got a bright light and cheaters I realized I had switched a couple of wires around. Once I got that ironed out, all worked beautifully. The customer service is great and fast shipping. Highly recommend for plug and play harness. Takes about an hour from start to finish and wrapping everything up neatly.

5 wire Harness 2019 Tri-Glide

Jeff Hughes on Mar 17th 2021

The kit came complete and was very easy to hook up. I, myself made an error when plugging in the colored wires to the properly numbered wires. I goofed and miss-read one of the numbers to color so I had some funky stuff going on with my trailer lights but it was totally my fault. I emailed Dale and he was Johnnie on the spot wit replies and was willing to help. When hooked up properly, the harness works great! Fast shipping and delivery. Very happy I bought this plug and play

Everything worked, I referred to the video several times during installation. I'll have to wait until spring to do final check out but I'm not expecting any issues.

Harley Trailer Wiring for 2017 Road Glide Special

Robert Stephenson on Oct 7th 2020

The wire harness was high quality and snapped in place without any problems. The instructions were very good but since I'm not an expert at electrical, I questioned Dale (the owner i think) and he reassured me I was on the right track. Both product and customer service was excellent. I recommend this harness and the company for supporting the customer. Bob S.
