What the heck is this???

I knew that you guys would come up with the answer. Thanks to all of you for coming to the rescue. The car did not start with the key, but I am changing all of the wiring anyway as it is a tangled mess of splices and electrical tape. I will try again tomorrow though.

Greendart72, thanks for the instructions on how the thing works, it really helps a lot to know the correct procedure!!! That page should be a sticky for all 74 owners!

Ramenth, I love the picture in my mind of all of the gov't. officials all standing around scratching their collective heads wondering how to get those 74 Fury's started!!! Serves them right!!!Thanks again, Geof
