I am having the worst time locating this. I have looked everywhere and no one has it, or can get it. I want to replace mine because the wires are frayed and stretched out. I also already have the trans out. I called atleast 12 places, with no luck. Ford discontinued it last year. I called two mustang junkyards and they both said the switch does nothing, and just screw the old one in there to have something in the hole. They said 90% of the cars that come in have it un plugged anyway. Does anybody know what the function of the switch is? And does anyone have one laying around. Thanks Ricky
