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.
For riders who prefer a custom wiring solution for their trailer, the NAMZ Custom Cycle Trailer Isolator with bare wires offers robust protection for your motorcycle's electrical system. This isolator prevents the common issue of overloading your factory turn signal module when connecting a trailer. It routes power directly from your battery, safeguarding your bike's sensitive electronics.
Why riders pick this
- Protects OEM turn signal module from trailer load
- Bare wire output for custom connector integration
- Powered by a robust 4-relay isolation system
- Draws power directly from the battery
- Manages brake, running, and turn signal circuits
This NAMZ Custom Cycle trailer isolator module is designed with bare wire outputs, providing maximum flexibility for custom trailer wiring setups. It employs a four-relay isolation system to draw power directly from your battery, rather than forcing your OEM turn signal module to handle the extra load of trailer lights. This proactive measure is crucial for preventing premature failure of your bike's factory electrical components.
Flexible Wiring for Any Trailer Setup
- Features a 4-relay isolation system for robust protection
- Bare wire output allows for custom connector installation
- Draws power directly from the battery, bypassing the OEM module

This peace of mind allows for more enjoyable rides, knowing your electrical system is protected.
