HI Tony! It's me again, I hope that you can read this message, I have already buyed the DIC for my Grand Prix and 0.0 is flashing, someone told me that I need two more wires to put in the harness but I have checked and the wires are there, in the position B6 and A7 (green and tan respectively), the one of the speedometer and the UART wire, you told me before that the DIC could not work and i think that this is the case, the seller told me that the DIC was tested before send it and function flawlessly but I do not know, do you know if there is a way to test if the wires have signal? or do you know which could be the problem? Thank you
