trailer brakes / electric brake wire not working
Okay folks, I need some help. I have a 2003 Expedition. I have the HD towing package and I have installed my brake controller under dash using the quick connector that came with the controller. The controller is getting power but I have no power (to the electric brake wire) at the 7-pin connector in the back of the truck. All the other lights (brake lights, running lights, turn signals) work and the trailer brakes work when connected to a different vehicle).
I assumed a fuse but have looked at the obvious ones (number 6 and 29 as identified as being related to the brake controller in the owners manual). I have also read the other posts to check for fuse 10 and relay 05 and 201 and 301. I can find fuse 10 and relay 05 and 201 but where is relay 301? I don't see it on the diagram for the fuse box on passenger side under dash. Any other reason there would be no power to the electric brake wire at the 7-pin connector?

Have you checked fuse #35 and #43? They provide power to the 4-pin and 7-pin connector at the rear of the truck.

I purchased a Haynes Repair Manual and was looking to check all of the fuses relays referenced above in this thread - I have checked all of them with exception of Relay 301 which is not in the passenger side fuse box. They Haynes manual indicates there are three other fuse boxes under the hood but I can only find one small one which is located right below the air cleaner assembly.
Where are (if there are any) other fuse boxes on this vehicle? 2003 Expedition
