Question:
If we use this item but the lights are on seperate pins in the semi plug.... Is there an adaptor to make the RV match the semi wiring . We use the semi commercially for work. And pull the RV very seldom. So we need to make changes on the RV side to match the semi wiring.

Expert Reply:
Adapter # HM47425 is designed to work with a vehicle or RV style 7-Way round pin so it would not work with the semi style 7-Way for the exact reason you mentioned; the functions are different.
You could install a separate 7-Way just for travel trailers using a hardwire harness for the lights such as # 119250KIT and then installation kit # ETBC7 for the 7-Way and provisions to install a brake controller.
