Hello John,
A great brake controller option is the Tekonsha Prodigy P3 Trailer Brake Controller - 1 to 4 Axles - Proportional # 90195. It doesn't have a remote, but it does feature a user-friendly LCD screen and is easy to adjust. One great benefit is that it can be programmed for different trailers, since each one typically needs a different intensity setting.
To make swapping the controller between trucks easier, you can use additional pigtails like the Replacement Brake Control Plug-In... view full answer...
In order to run the backup light into the cab, all you need is the Curt Trailer Connector Adapter - 4-Way Flat to 5-Way Flat - Vehicle End # C57187. This harness will allow you to convert your 4-way harness to a 5-way with the additional backup light pin.
If you currently have a 7-way installed, I recommend routing some spare wire from the reverse signal on your 2000 Peterbilt to the 7 way and then into the trailer's reverse lights. view full answer...
