Okay guys, I have a 1994 factory turbo truck. I have the factory plug to plug in a brake controller under my dash. When I bought my car trailer a few weeks ago the guy gave me this Brake Force brake controller http://www.amazon.com/Hopkins-47225-Brake-Force-Brake-Control/dp/B000BQWJFW So I installed this along with this Hopkins patch harness to plug in between the brake controller and the truck's plug http://www.amazon.com/Hopkins-47715..._1?s=automotive&ie=UTF8&qid=1334755310&sr=1-1 I also varified that I have the fuse installed in slot 21 in the power distribution block under the hood. Is there anything else I am missing? When I push the brakes a yellow light comes on on the brake controller but it does not seem to be engaging the trailer brakes, I do not hear any sort of clicking at the front axle (where the brakes are). Any advice on this? I am new to trailer brakes and I know a bunch of you guys haul stuff regularly. I would appreciate some help, because I towed a ford expedition home last week and it was not fun to do with out any extra braking help. Thanks.
