Absolutely, Larry!
You just need the Replacement Braking Indicator Light Kit # RM-300065-00 for the light itself, and then we have the following wires that get you from the light on the RV to the brake system on your towed vehicle:
- 50' Monitor Wire # RM-450008-50 (RV side)
- Patch Cord # RM-450008
- 15' Monitor Wire # 450008-15 (car side)
Anything else?
