This US-made isolating trailer wiring harness has components developed specifically for Indian motorcycles to power trailer lights, protect the bike's computer and avoid fault codes. Compatible models include the Roadmaster, Chief, Chieftain, Springfield, etc. 

This kit works with 4-wire trailers that have combined brake lights and turn signals. 

Beginning in 2019, Indian introduced a revised tail light pattern for some bikes that combined the brake signal with the turns and eliminated the separate brake light. This change affects the type of components needed for your trailer wiring kit. When you choose your kit, tell us which type of tail lights are on your bike.

Based on your choice, we’ll send the appropriate set of components which may differ from what is pictured. Indian 4 wire kits for the New School Style lights do NOT require a CAN bus decoder module.

When I received the product, I had some issues with getting it to work on my Indian. Dale at Open Road Outfitters answered my emails and questions over the weekend. Got everything lined out and I'm happy with the product. Shout out to Dale

Good so far

Easy install, seems to work well so far. Glad to find a harness for Indian. Especially one that converts the 5 wire system to 4 wire.

Great Service

After ordering this it3m and the related hitch, I had a question about trailer pulling capacity. I used the online tool and received a personal response from Dale that was very helpful. He was a difference maker in my buying experience. Thanks.
