Expert Answers about Winnebago Solis NPF Motorhome

• Availability of Custom Wiring Harness for Brake Controller Installation on 2023 Winnebago Solis 59P
• It sounds like you're looking for a custom wiring harness like the # 3024-P to install a brake controller in your 2023 Winnebago Solis 59P. Even with the factory 7-way they did not add a plug and play connector on the Promaster 2500. The only option would be to find the correct wires and splice them in. If you don't want to try to figure out where the correct wires are located you could always use a brake controller like the Curt Echo # C51180 which plugs into your 7-way at the rear.
