Good question.

You will need the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 and the Roadmaster Brake-Lite Relay Kit for Towed Vehicles # RM-88400 to sync your lights between vehicles.

You need the relay kit because you are using a supplemental braking system like Demco SBS Stay-IN-Play DUO Supplemental Braking System - Proportional # SM99251
