Trailer isolators easily and properly connect your trailers
lighting while removing the electrical
load from the motorcycles factory wiring, fuses, relays, computers and
electronics. We created the
modular design of separate Isolators, Sub-Harnesses and Converters. The advantage is that you can accommodate a 5 wire or a 4
wire trailer and exchange the sub-harness for another model of motorcycle should
you trade the old bike in. All of our electronics are made in the USA.

The isolator is the main
component. And ours is made in the USA. Tennessee to be exact.
Ours are epoxy potted for weather resistance using Omron components.
Omron is an OEM supplier to most all the major automotive and motorcycle
We use the best component available for the job; in fact, Toyota uses the same
component for power window switching.
The sub-harness connects to your bike on one end and the Isolator on the other.
This makes the connection "Plug & Play" so you don't have to splice.
In order to make a
complete kit, you must order the 07660 Isolator and one sub-harness

How do you tell if you need it? Look at
the wiring plug on your trailer - does it only have 4 wires? If yes, then
you will need it.
Installation simply requires you to plug it in-between the Sub-Harness and the
Isolator and then connect one wire to ground.
Going to a 4 wire setup is completely
reversible by simply unplugging the module to revert to a 5 wire system.
Adding the converter only utilizes 3
of the 4 circuits in the isolator - the design allows the 4th circuit to power
Our converter will work with LED lights since it is active electronics.
