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.

Isolator 
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 manufacturers. 
We use the best component available for the job; in fact, Toyota uses the same component for power window switching.

Sub-Harnesses
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 listed below;

Trailer Light Converter (5 to 4 module) 
If your trailer is a 4 wire setup (has combined brake and turn signals), you also need our made in the USA converter.
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 an accessory.   
Our converter will work with LED lights since it is active electronics.
