Trailer " auxiliary " power not working
I have a 2000 X with the factory installed tow package. The auxiliary power does not seem to work. I have a enclosed car trailer, that has inside 12VDC lighting. When plugged into the truck they are supposed to work, they do not. I do not seem to be getting voltage on that pin on the 7 pin connector. I checked the fuses under the dash, and all are good. I know there are more, but I do not have a owner's manual. All exterior trailer lights work fine, brake, turn, running etc...

You need to check the underhood box by the master cylinder that partsetal was talking about. You need to make sure you have a 30 amp maxi fuse in position 115.
Also, I think there may be another small relay box next to the big one that holds 4 relays. Two are for the ESOF and two are for the trailer brakes and trailer tow charge. They aren't in the owner's guide for the Excursion, but I know they were there on my 99 F250. You may want to check and see if they are there and working.
