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 a trailer with your Harley-Davidson requires a robust electrical connection that protects your bike's sensitive systems. The NAMZ Custom Cycle 8-Position Trailer Isolator is engineered to prevent electrical interference and parasitic battery drain, ensuring a smooth towing experience.
Why riders pick this
- Isolates trailer wiring from motorcycle electrical system
- Prevents signal interference and parasitic battery drain
- 8-position connector configuration for reliable connection
- Direct fit for specified Harley-Davidson Touring models
- Essential for towing trailers with modern lighting
This NAMZ Custom Cycle trailer isolator is a critical component for 2014-up Harley-Davidson FLHTCUTGSE and 2015-up FLTRT models equipped with a trailer. It features an 8-position connector configuration designed to completely isolate your trailer's wiring from your motorcycle's electrical system. This isolation is crucial for preventing common issues like signal interference, flickering lights, and parasitic battery drain, especially with modern trailers equipped with complex lighting and brake controls. Installing this direct-fit isolator ensures both your bike and trailer's electrical systems operate independently and reliably.
Reliable Trailer Electrical Management
- 8-position connector configuration for comprehensive trailer integration
- Isolates trailer circuits to prevent electrical interference
- Eliminates parasitic battery drain from connected trailers
- Direct fit for specified Harley-Davidson Touring and Trike models

Protect Your Investment
Modern motorcycles and trailers both have sophisticated electrical systems. Without proper isolation, these systems can interfere with each other, leading to frustrating issues and potential damage. The NAMZ Custom Cycle trailer isolator provides peace of mind, allowing you to tow your trailer confidently. It's an essential upgrade for any rider who frequently tows, ensuring the longevity and reliability of your Harley-Davidson's electrical system.

Common questions
Will my trailer lights still work without this isolator?
Yes, but the isolator prevents electrical interference, flickering lights, and battery drain issues that can occur when trailer circuits share power directly with the motorcycle's electrical system.
Do I need this if my trailer is LED-equipped?
LED trailers especially benefit from an isolator. LEDs draw less current, which can sometimes confuse a motorcycle's BCM (Body Control Module), leading to error codes or improper light function without proper isolation.
What Harley-Davidson models does this trailer isolator fit?
This isolator is a direct fit for 2014-up Harley-Davidson FLHTCUTGSE and 2015-up FLTRT models equipped with factory or aftermarket trailer wiring harnesses. Please confirm fitment for your specific year and model.
