Pricing and production model updates!!!! After some time we fiqured out a way we can use 1 single harness using the 7-pin round trailer socket, and still be able to gain both reverse light activation and running light activation, as well as a OFF mode. Because of this, we are dropping the 4-pin option all together, and will include this new harness and 3 position switch on ALL packages, thus reducing options and end cost. Making these fully equipped for all your needs.
