I have linked a video install of a brake controller that also shows the installation of the Tow Ready Custom Fit Vehicle Wiring,...

  • Installation of a Brake Controller and 7-Way on a 1997 Ford F-150
  • First, many brake controllers actually come with a universal harness with one end that plugs into the back of the controller and on the other end are just blunt cut wires, no plug. Some vehicles that can have a plug will have an optional harness, sold separately, that has a plug on each end. Your 1997 Ford F-150 could have had a factory brake controller connector to plug in a controller but it sounds like it was removed. If anyone has that part it would be a Ford dealer. But it isn't something...

  • How to Determine Wiring Functions on a 1997 Ford F-150
  • In order to determine the wiring functions on your 1997 Ford F-150, you are going to have to use a circuit tester like # PTW2993 if needed. Have someone run through the various functions in the truck while you test with the circuit tester. The problem is that vehicle manufacturers can use any color wire they want for any purpose, and it changes from year to year and sometimes even within the same year (I have seen it). Because of this there is no standard and testing is the only way to...
