Allows you to connect aftermarket electrical and lighting accessories with total confidence. Completely isolates the accessories from the vehicle’s main wire-harness without adding any additional load to the system. A must-have on newer BCM/VCM/CAN bikes that have very sensitive electrical systems that do not allow the addition of electrical or lighting accessories. Has an built in integrator function which combines brake and turn onto one wire, giving turn priority over brake which is very useful for adding Run-Brake-Turn function to a 3 wire LED (low-high-ground). There is also a built in trailer out which can be connected to an optional 4 pin trailer harness (sold separately) given you complete and total confidence of a 100% isolated trailer connector from the vehicle. Total Isolation of all lighting and electrical accessories from vehicle. Left Turn, Right Turn, Brake, Battery, Accessory Power Inputs. Isolated Outputs: Left Turn, Right Turn, Brake, Run/Accessory. Isolated Integrated Output: Turn/Brake Output. Plug and Play (except for universal version). 45 Amp Max Total Capacity.
