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.
