So ok...tonight I put the 40 amp fuse in under the hood in the far left(left or #1 if standing over the fender). Didn't seem to do anything. Left it in and hooked up the trailer and plug to the truck(But not the emergency wire, its too short), and still no power to brake controller. Pulled the connector plug from the box under the dash(plug says 2003-current but Oreilly's book said it would work, im not quite sure but anyways). Connected a test meter to the probes in that section of the box and didn't get any power. Connected the test meter to another section of the box(not the one this controller is supposed to connect to), and I got power. Now it is dark, had no supper, tired, and ready for bed. Can anyone think of what I should try next? Thanks again for all your help. Oh, btw, I removed that box from under the dash, and that particular plug IS wired, but now power for some reason.
