2008 F 150 Brake Controller Question
I just purchased a 2008 F 150 Lariat and I am installing my brake controller. The truck came with the tow package and the 3.73 axle. Will I need to add any fuses or relays to power the brake control...

Both my F-150s as well as the 2011 models I test drove all have two relays in a bag in the glove box. One for 12V trailer battery charging and the other for trailer brakes. The previous owner may have installed them already, but not likely if no brake controller. Check the owners manual for which fuses in the distribution box and then check your actual distribution box underhood.
