How To Wire Tow Vehicle with Separate Brake/Turn Lights to Motorhome with Combined Lights

Question:

Is there a certain part that converts a combined brake and signal to the towed vehicle that has seperate brake and signal and bulbs. I already have a road master tow bar

It sounds like you need a diode kit, the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit part # RM-15267 or part # RM-154. The Roadmaster Diode Kits will combine the separate brake/turn signal circuits on the vehicle so you can power them from the motorhome with combined brake/turn signal circuits. Once the Roadmaster Diode Kit is installed, the brake light bulb will also double as the turn signal.

The main difference between the Roadmaster Diode Kits is that the former has extra circuits for a battery charge line for example whereas the latter only contains circuits for the basic lighting functions. If you need any other parts for your flat-tow setup please just let me know.
