Hello Anthony,
Thanks for writing in!
For your 2025 Thor Quantum motorhome on the Ford E-450 chassis, you will want the Redarc Tow-Pro Liberty Brake Controller w/ Universal Wiring Harness # RED52VR, so you got the correct brake controller ordered. This brake controller is going to work great for your single axle car dolly.
The # RED72CR you were looking at is for Toyota models.
I also see that you ordered the Redarc Plug-and-Play Wiring Harness # 331-TPH-007. We do not have that harness listed as a confirmed fit for your 2025 E-450, but that does not necessarily mean it won't work. Since you have already located the factory brake controller connector behind the coin holder, I attached a close-up picture of the connector on the # 331-TPH-007 for you to compare with yours.
Were you able to compare the two connectors? Does it look like they are going to match up? I am very curious to know so I can get it added to our fitguide =)
