Product Details

Choose your trailer wiring: The 5-wire kit includes the sub-harness and isolator. The 4-wire kit also includes the 5-to-4 converter. The converter is included only when the 4-wire option is selected.

Now updated to include 2020 and up models.

Isolators easily and properly connect the lighting from your trailer, sidecar, trike, etc. while removing the electrical load from the motorcycles factory wiring, fuses, relays, computers and electronics. Proper isolation of electrical loads will help you to not void any factory warranty.

Our design is a modular daisy chain of a separate sub-harness, modules and the Isolator. The advantage is that you can accommodate a 5 wire trailer, a 4 wire trailer, or swap sub-harnesses should you sell your current bike. All our electronics are made in the USA.

Slingshot Specific Can-bus Module
The brake lights on your Slingshot by the Body Control Module (BCM). The output is a constant 2.5 volts even when the brake lights are not on.. This is not the standard method. Our module takes the BCM wiring and creates output that can be easily used by our Isolator. Most importantly, it works in the background and is not detected by the vehicles Canbus system and therefore does not create any service codes. This item is required for installation.

Sub-Harnesses
The sub-harness is the first part. It 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.

Isolator
The isolator is the main component. And ours is made in the USA. Tennessee to be exact.
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.

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 it’s required.
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.
