Lighting Converter for Motorcycle Towing 4-Pole Trailer

Question:

I have a Pollak 5 pin round connector on my motorcycle and am looking for an adapter to a 4 way flat connector on my trailer. Do you have such a product?

We do not have any trailer wiring adapter that converts the 5-pin round format on your motorcycle to a 4-pole flat type. The reason is that your motorcycle uses separate stop and turn lights while the 4-pole trailer lighting format combines these into a left stop/turn and right stop/turn circuit.

You have two options: adding separate turn lights to the trailer OR installing a converter that takes in the bike's separate signals and combines them into the trailer 4-pole format. Roadmaster part # RM-732 takes in the separate signals from the motorcycle and combines the stop/turn circuits at its output.

At the converter's output side you will need to splice in a vehicle-side 4-pole connector # C58044 to match your trailer. Mount the converter in a safe protected spot on the vehicle and carefully wrap all splices with electrical tape. Note that your running light wire on the bike bypasses this converter completely; it connects directly to the 4-pole's brown wire.
