I recently purchased a used Jeracho truck cap for my 2011 GMC Sierra. The truck cap has a third brake light and a dome type light with a switch on it. The wiring for these lights runs into a 4 prong type connector similar to trailering connectors I have seen. This connector sits just inside the door of the truck cap on the left side.
My truck has a trailering package with the 7-prong connector. Does anyone know an "easy" way to connect to the 4-prong connector in the topper to get power to those lights? On my old truck I remember splicing into the parking light wiring to get power to a dome light. Just wondering if anyone has any suggestions.
