That may be it, although my guy thought it still may be stock. The arm on the steering wheel sure looks stock and matches what is in the owner's manual. 
�
The arm has a black thick wire (probably bundle of wires inside) that goes up and around to a black box. The black box had an old label that said something to the affect: "AT Magnet...Servo..." Memory is hazy.

On the rear of the speedo head there should be a white sensor with two
prongs sticking out.� It is held on by two small phillips head screws.
That is the speed sensor for the stock cruise control.� Maybe the problem
we are having is that you have an aftermarket cruise system?� That would
get the speed sense from a magnet on the rear CV axle instead of at the
speedo head.� It also probably wouldn't have the switch I am talking about,
instead it would be using the brake light switches and just be spliced into
that.
