Years ago I had my rear built for the track. The guys that built it went into the computer and turned off the traction control so it cannot be turned on or off at the dash button. Since then I put a Detroit trutrac carrier in the rear. My question is can I turn the dash switch back on and will it still work with the new carrier. Also since it was turned off my cruise control has not worked, Is it related in any way. If I can turn on is there software needed in order to do so?
