In regards to the Roadmaster Tow Dolly with Electric Brakes (RM3477) part # RM-2050-1, the correct replacement spindle is part # RM63FR, the correct replacement braking assemblies are part # RM-4701-R for the passenger side and part # RM-4701-L for the driver side, and the correct brake drum is part # RM43FR.

Unfortunately, we don't offer any relay harnesses for this tow dolly as they are not available as replacement parts so you'll need to re-wire this yourself or hire a professional.
