Yes I have now finally found it,,,
The info here (site) wasn't real clear for us first timers looking,,
BUTTTT,,,For the NEXT lost soul,,,
On a 98 "SPORT" If you take the knee panel off (the plactic under the steering coulum) You will see a sheetmetal panel/frame, and on the right had side.
You should see 2 screws. You can NOT SEE the box as it is on the other side of metal frame,,(almost under the ash tray) an the timer/module slides out (or down in this case) Like PMJ2500CTD said above.
It is about the size of a ciggerate pack. It is a circute board inside of a black plactic box.
An mine had the PART # 56020157AB,,I flew to my dodge dealer before it closed,,$150
SOOOOooooooo
I said to my self,,"SELF" I said,,,go look in a salvage yard,,,,,,,:-laf
I HOPE THIS HELPS THE NEXT GUY (or gal)
