About NAMZ Custom Cycle
NAMZ Custom Cycle builds plug-and-play wiring harnesses, extension kits and electrical components for Harley-Davidson. Its handlebar extension and connector kits are what make an ape hanger or bagger bar swap a bolt-in job instead of a splicing project.
Towing with your Harley-Davidson Tri Glide demands reliable electrical performance, and the NAMZ Custom Cycle Trailer Isolator delivers just that. This essential component protects your factory turn signal module from the increased load of a trailer. It ensures that your Tri Glide's electrical system remains robust and functional, preventing costly repairs down the road.
Why riders pick this
- Protects OEM turn signal module from trailer load
- Routes trailer signals through a 4-relay bank
- Draws power directly from the battery
- Available in 5-wire or 4-wire flat connector options
- Designed for 2014-up Harley Tri Glide models
The NAMZ Custom Cycle Trailer Isolator for Harley Tri Glide models from 2014 and up is specifically engineered to handle the unique electrical demands of a trike towing a trailer. It routes all trailer signals through a dedicated 4-relay bank, drawing power directly from the battery. This critical isolation prevents the trailer's electrical load from overtaxing your OEM turn signal module, which is a common cause of premature failure. Available in both 5-wire and 4-wire flat connector configurations, you can choose the option that perfectly matches your trailer harness.

Maintain Peak Performance on Your Trike
Your Harley Tri Glide is built for the open road, and adding a trailer shouldn't compromise its electrical integrity. This NAMZ trailer isolator is an indispensable upgrade for any Tri Glide owner who tows, ensuring that your bike's sensitive electronics are shielded from excessive current draw. By providing a clean, isolated power source for your trailer lights, it helps maintain the longevity and reliability of your Tri Glide's electrical system, letting you ride with confidence on every journey.
