Chances are you have one on your T-5. They've been making T-5s for over 30 years and have hundreds of variations some like the SN-95 mustang t5 didn't but others did. I don't know if the switches were always in the same place on different castings. I've heard tell the tko and the t5 use the same switch with different part numbers. TKO 2606244. t5 13001400004/E6ZZ7A247A. Part of the t5 number could be for the stainless pin under the switch. Some use the switch for the cruise control, don't know how. There was also a 5th gear sensing switch, with computer cars I would imagine
