If your E450 Van Cutaway Chassis is a 2009 to 2020 model year, you'll need the Curt # C51432 harness to connect the # C51170 Curt Spectrum Brake Controller to the factory plug located behind the cubbyhole in the dash.

If your van chassis is a different model year, please let me know and I'd be happy to make a recommendation.

I've linked to a product description video that explains the features of the Curt Spectrum Brake Controller.
