Roadmaster makes a great and reliable product and the Roadmaster Brite-Lite Wiring Converter # RM-732 is going to be the most reliable 3 to 2 converter that we have available. It features a heavy-duty aluminum heat sink design that effectively dissipates heat and outlasts other brands.

The trailer connector used on most semi-tractors is a 7-pin round which is similar to a 7-way flat used on most RV's but the big difference between them is how the stop and turn signals are wired. The stop and turn signal circuits are separate on…

I show that for a 2007 GMC Sierra 1500 new body style, you will need to use the Roadmaster 4-diode kit, #RM-154. Your truck has a 2 wire system (combined brake and turn circuit) so additional diodes are not needed. There are diagrams on the product…

Answer 6

Since your light plugs into a 7-way round you'd actually need the opposite adapter than the #F77R. Which for that you'd just need the part #PK12728.

A 4-Way trailer connector has the basic lighting functions only; running lights, left turn signal and brake lights, right turn signal and brake lights, and ground. A 7-Way has these functions and a 12 volt circuit, a circuit for electric trailer…

Answer 10

Since wire color codes are NOT universal, we always recommend wiring by function, rather than wire color. If you look at the Trailer Wiring FAQ article I have linked you to, you can see some diagrams showing the proper way to wire a vehicle and…

Answer 11

Either way is correct. It depends on if you want to keep the semi-style 7-Way (if you need to tow that type of trailer) or if you will never be towing a semi-trailer. If you need to keep the 7-Way semi active on the truck, then you would need to make…

Answer 12

It sounds like you are speaking of the wires for the brake magnets. If this is correct, you will need to connect one of the wires to the brake controller output wire on your trailer connector and the other wire will need to be grounded to a clean…
