I did a very little serch in hopes to help you Gary. See if you can read through this and apply any of the suggestions they gave. Maybe this could help..
There's a convertible top motor wire, white with a violet stripe as I recall, under the center concole/shifter bezel on '99-'04 models that's a switched 12V power supply wire. Ford graciously provided it in all models, vert or HT, for our accessories.
