add circuit to existing fuse box?

ref 98 xlt 4-door
It was easy to install a 12v outlet in the rear compartment, then run the wire under the door sills to the front of the car. I hoped I could run it straight to an unused location on the factory fuse box, but what a mess. I finally have the fuse box loose and can barely see the back of it with its short tangle of wires. One fuse 22 is labeled 'auxiliary power socket'. It has a black wire with pink stripe. I don't know that I have an 'aux power socket', so this seems like the perfect place to connect the one I'm adding. Anybody know:
1) what that wire would currently go to
2) how in the sam hill do I get their wire out of the fuse box and mine in
3) and/or where could I find that black/pink wire somewhere else in the car where it's easier to splice into?

If that doesn't work out, I can still try to get through the dash to the engine compartment and connect to the back side of the fusible link with an inline fuse. Not as esoteric, but it would work.

open to suggestions...

Do you have a 12 volt socket other than the normal cigar lighter? If so I would assume thats where the wire goes. To get the wire into the fuse box, I'd simply get a fuse tape. It goes onto the blade of the fuse and allows you to use a connector to hook up to it. They usually come in straight and 90 degrees. Getting into the engine compartment is fairly easy. There is a round wire grommet right around the brake pedal.

Thanks for the response. Everything's connected now and working great.

Happy 4-wheeling!
