Complete mid frame wiring system with billet cover that mounts the power module and DOT auto cancel module in one location. Includes integrated load sensing, auto-canceling, control module. Replaceable start relay and diagnostics LED's which can be viewed through holes in the housing.  This is similiar to the WP181 except that it has seperate turn signal and running light wires.  The rear turn signals will not work as brakes, or running lights.
