The BCM probably has the BCM harness TSB performed which adds a small sub-harness containing fuses for left/right and brake....Those fuses are under the lower dash right by the steering column

I have an 06 SE off road with the big tow and when installing my brake controller I hooked up the adapter to the factory pigtail with the key off. I hit the brake pedal with the wires while trying to route them and they sparked. I figured I blew a fuse. When I hooked up the brake controller it didn't work. When I checked the red wire from the pigtail it was dead. I looked in this thread and found the wiring diagram and was able to find the blown fuse. The diagram states it is a "fusable link" but what I found when trying to replace the blown fuse is that it is a "Dealer only part" $15.99 and had to order(of course!!) I guess what I am trying to say is I have power to my brake controler and it is wired up to the factory pigtail. When I push the manual lever to the left my brake controler red light comes on and I have power going to the 7pin connector at the bumper. I just want to share my experience to help other TITAN owners. I was frustrated not being able to find the correct fuse. By the way it is it he rear fuse box on the engines right(passenger side) look at the inside of the cover for the diagram. It is labeled "Electric brake controller" It really stinks to replace this fuse because it also runs the radiator fan and ignition switch. This fuse is three in one. I needed mine to pull my 3 horse goose nect trailer so I soldered it back together in a pinch( ordered a new one today) Hope this helps someone else!!!
