Where are the power and ground wires on a 1998 ford explorer sport?

OK, just bought the truck and I'm trying to put in a Kenwood CD player it has red and yellow wires for the power and black for ground. The CD player works fine, the fuse is fine in it too, now the owner before me cut all the wires on the truck and CD player. I've tried every wire and nothing. Is there another fuse located in the truck somewhere for the radio besides the the one in the back of the stereo? I've looked at the fuses on the driver side door but it doesn't mention anything about stereo/radio fuse, please help as soon as possible, every answer is appreciated

There's a great deal of information and a bunch of wiring diagrams on this page at the 'install doctor'.
