Question:
I purchased a C24VV and the wiring adapter to go from my Ford F-150 connector to the unit. I have no display not even a dot with and without the trailer connected

Expert Reply:
The install harness part # C51436 is the correct harness to install the Curt Triflex part # C24VV in your 2018 Ford F-150. What I would do is verify the controller wiring has power on the black wire as this is the power circuit for it. You'd want to use a circuit tester like part # PTW2993 for this. If there is no power there then check under the hood for a blown fuse for the brake controller power circuit. If there is power there then you most likely have a bad brake controller as with power and ground it should power on.
I attached a help article on troubleshooting brake controller installs for you to check out as well.
