There is no special switch, at least for the taillights (that you can turn on and off)and I am not positive about the pushbutton cars, but on my 74 there are 2 rheostats that control instrumentation lights. There is one at the top left of the center console gauge panel and one right above your left knee as you are sitting in the car next to the knob that resets the trip odometer.I agree with Charlie that you should start with the fuses, they are very susceptible to corrosion and go from there.
I would also suggest you contact the vendors and get an owners manual, shop manual, tech service bulletins and wiring diagram. All of these are available in reprints and are invaluable when owning one of these cars. The sponsor of this website has a great new resource book out for $20.00 that includes parts diagrams for the car and the ZF tranny. The parts book has blow-up diagrams and utilizes the parts numbers that DeTomaso used that many of the vendors also use. Makes it real easy to order a part, you identify it with the parts book and tell them you need a 23008A instead of trying to describe the thingamabob attached to the whozit up under the left side of the dash (is that passenger or driver side)? These things (and this forum)will do a great deal to make your experience with these great cars more enjoyable. I would also suggest joining both POCA (Pantera Owners Club of America)
http://www.panteraclub.com/home.htm and Pantera International
http://www.panteracars.com/home.html. They both are about $60 each per year and you will get info on local clubs and they print magazines with news and technical tips that are of interest to the Pantera community.
Good luck with your new toy and welcome to the Pantera community!
