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.

When you're towing a trailer with your Harley-Davidson Road King, the extra current draw can put a strain on your factory turn signal module. The NAMZ Custom Cycle Trailer Isolator is engineered to prevent premature failure of your OEM electronics. It provides a dedicated power path for your trailer lights, safeguarding your bike's electrical system.

Why riders pick this

  • Protects OEM turn signal module from trailer load
  • Draws power directly from the battery via relays
  • Features a 6-pin Molex connector output
  • Handles brake, running, and turn signal inputs
  • Designed for 2014-up Harley FLHR Road King models

This NAMZ Custom Cycle Trailer Isolator features a 6-pin Molex connector, making it a direct fit for 2014-up Harley-Davidson FLHR Road King models. It pulls power directly from your battery through a relay system, ensuring your trailer lights operate without drawing excessive current through your bike's sensitive OEM turn signal module. This isolation is critical for maintaining the longevity and reliability of your motorcycle's electrical components when towing.

Reliable Trailer Light Management

  • Powered directly from the battery to reduce strain on OEM electronics
  • Relay-switched brake and turn signal circuits for stable power delivery
  • Protects the OEM turn signal module from increased trailer load
  • Accepts left, right, brake, running light, and ground inputs for full functionality

Essential Protection for Your Touring Rig

Adding a trailer to your Road King increases the electrical load, and without proper isolation, your factory turn signal module can be pushed beyond its limits. This NAMZ isolator is a smart investment for any rider who tows, ensuring your bike's electrical system remains intact and functional. It's designed for straightforward integration, allowing you to focus on the ride ahead, not electrical issues.
