Never mind DD I figured it out by looking at the pictures of the products on Radio Shacks web site. Looks easy! the holder costs $2.50 and the 9 volt clip cost about 2 or 3 bucks. Cheap and easy! ;)

It IS quick and easy.  Still I'd recommend putting a fuse clip of some kind in the line.  I used a small blade fuse unit and carry a couple of spare fuses on a trip.

OK.  That's the easy part.  Cutting out 20 or so feet of transponder cable and splicing it back together ... that's a bit more tedious.
