So I recently bought my '99 gt with a trashed rear diff and a hydroboost problem. While changing the hydroboost I managed to break the cruise control cutout switch. I grabbed a spare from a buddys 04 mach. Now that the car has a freshly rebuilt rear and functioning brakes, I now know the cruise doesnt work. Looking on ebay, the switches are listed as 2001-2004. So is the one off the mach wrong for my car and is this why my cruise isnt working? The cable is connected, and fuses are good. If this is in fact the case, where can I buy the correct switch for a 1999?
