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.
The NAMZ Trailer Isolator is an essential upgrade for Harley Touring and Softail riders who tow, safeguarding your motorcycle's electrical system. This relay-based module pulls power directly from the battery and relay-switches brake, running light, and turn signals to your trailer wiring. This design ensures that your OEM turn signal module is never overloaded by the additional current draw of a trailer.
Why riders pick this
- Protects OEM turn signal module from trailer overload
- Four-relay isolation for reliable power switching
- Draws trailer power directly from the battery
- Prevents costly electrical component failure
- Designed for Harley Touring and Softail models
Factory turn signal modules on Harley-Davidson Touring and Softail models are not designed to handle the increased current draw of a trailer's lighting system. Without an isolator, this extra load can lead to overheating and premature failure of expensive OEM components. The NAMZ Trailer Isolator provides a robust solution, routing all trailer lighting power through its dedicated four-relay isolation bank.
Robust Electrical Protection for Your Ride
- Four-relay isolation bank protects sensitive OEM turn signal modules
- Draws all trailer electrical load directly from the battery, not factory circuits
- Prevents costly premature failure of your motorcycle's electronics
- Ensures consistent and reliable trailer light operation
Engineered for Harley Touring and Softail
Designed specifically for a wide range of Harley-Davidson Touring and Softail models, this isolator offers peace of mind for riders who frequently tow. Its compact housing makes for a clean installation, and by directing trailer current away from your bike's sensitive electronics, it helps maintain the integrity and longevity of your motorcycle's electrical system. Confirm your trailer connector type to ensure proper setup.

Common questions
Why do I need a trailer isolator instead of wiring direct to the OEM turn signal module?
Factory turn signal modules are not rated for trailer current draw. An isolator protects the module from overheating and failure, which typically costs hundreds of dollars to replace.
What Harley-Davidson models does this isolator fit?
This isolator is designed for various Harley-Davidson Touring and Softail models, including Road King, Electra Glide, Street Glide, and Road Glide. Always confirm fitment with your specific year and model using our Shop by Bike tool.
Does this come with a 5-wire or 4-pin connector?
NAMZ offers both 5-wire and 4-pin flat connector output options. Confirm your trailer connector type before ordering to ensure you receive the correct configuration.
