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 with your Harley-Davidson Tri Glide demands reliable electrical performance, and the NAMZ Custom Cycle Trailer Isolator delivers just that. This essential component protects your factory turn signal module from the increased load of a trailer. It ensures that your Tri Glide's electrical system remains robust and functional, preventing costly repairs down the road.

The NAMZ Custom Cycle Trailer Isolator for Harley Tri Glide models from 2014 and up is specifically engineered to handle the unique electrical demands of a trike towing a trailer.
