Question:
I have a 2023 Mercedes-Benz Metris Cargo Van with Factory Towing Package. It came with a 7-pin trailer connector, but I need to add a trailer brake controller. Your website only lists brake controllers for without factory Tow Package. I want a controller for use WITH factory Tow Package, and I want an adapter cable to connect to the factory wiring under the dash.

We do have the brake controller solution you are looking for your 2023 Mercedes Metris. The install harness part # 3063-P will connect to your factory brake controller wiring and will let you install a Redarc brake controller like the Redarc Tow Pro Liberty part # RED24FR. This is a really nice brake controller that only puts a small knob on the dash and performs really well.

Wrong! the Brake controller you mention does not plug into the liberty model. It is said to work on the more expensive one.
