Ok I've checked every fuse, even consulted the owners manul for fuses I might be missing. I can't find anything wrong, the wiring looks good. I ve checked all the relays and added the appropriate ones under the hood. What I'm talking about is my brake controller. I used the factory supplied pigtail in the glove box. The Truck came with a towing package ( '00 F150 ) and I found where the little plug in goes under the dash BUT I still get no lights, nothing from the brake controller. Any web sites you guys know about to troubleshoot this?
Thanks!

 

I had the same problem with my F250. It ended up to be 1 wire in the pig tail under the bed where the 7-way connector plugs into. it was corroded and I had to remove it sandpaper it. works fine.
