Steering Column Switch: 88 & 89 Pontiac TA w/Radio ControlsThis is for the 1988 & 1989 Pontiac Firebird TA & GTA (& Turbo TA.. if your got one). its the steering column cancelling cam assembly.. with the four pins for radio control connection. SORRY about the price of this.. but this is the LAST one.. and there really is bugger all left in the world new.. GM has discontinued them.. a rare switch assembly.. and there is nothing we can do about it
