I checked your order notes and it looks like you ordered a Prodigy P2 part # 90885 and an install harness part # 3035-P for your 2004 Ford F-150. These are the correct parts for your truck, so most likely your problem is a blown brake controller fuse or relay under the hood of your truck. The harness should provide power for the controller once it is snapped into place.

The other possibility is that the harness just didn't click all the way into place on either the truck end or the trailer side.

I attached an install video for this harness that shows it being used to install a controller in a 2004 F-150 just like yours.
