Anybody know what they could be for?? Looks like there is a blue, black, red and yellow wire. These were taped to that other group of wires with some white tape. I pulled the white tape off but you can see the residue of the tape on the black electrical tape of other wires.

 

They are accessory feed through wires. If you look inside around the steering column, you should find the other end. Since some people add accessories to the X, Ford provided 4 wires in a feed through wire harness from the engine compartment to the cab so you do not have to poke holes in the firewall.
