Jumperless ALDL 12-pin USB Cable This cable works on carsNEW Jumperless ALDL Cable! Many 1990 and newer vehicles do not need the 10k resistor to start data flowing. For a sleeker look, easier operation, and lower cost, we have an option for the ALDL cable without the jumper block. In all other respects it is identical to the regular ALDL cable. If you are unsure if your vehicle need the 10k resistor, please order the regular version. Otherwise, save some money and try the jumperless version!
