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 Custom Cycle Trailer Isolator is a vital component for Harley Touring riders who tow, preventing damage to sensitive factory electronics. This system intercepts brake, turn signal, and running light signals from your battery, routing them through a bank of four dedicated relays before sending them to the trailer. This effectively shields your OEM turn signal module from the extra electrical load of trailer wiring, preventing premature failure and expensive replacements.
Why riders pick this
- Protects OEM turn signal module from overload
- Draws power directly from the motorcycle battery
- Four-relay bank isolates trailer signals
- Processes brake, turn, and running light circuits
- Available in 5-wire or 4-pin flat configurations
Towing a trailer places an additional demand on your motorcycle's electrical system, often exceeding the capacity of your OEM turn signal module. The NAMZ Trailer Isolator is engineered to mitigate this risk, ensuring your factory components remain protected. By drawing relay power directly from the battery, it handles the trailer's current independently, preserving the longevity and functionality of your Harley's original wiring and modules.
Superior Electrical System Safeguarding
- Draws relay power directly from the battery, not the OEM turn signal module
- Utilizes a bank of four relays to isolate and process all trailer light circuits
- Protects your factory turn signal module from damaging current overload
- Processes brake, turn signal, and running light circuits efficiently
Designed for Harley Touring Models
