Msg to Roy. Thx u roy, so far, there is no blown fuse, cigar lighter has power, question, does this paticular vehicle 12 pin DLC have to have a power wire in order to use a scanner to read the codes? Terminals A and B, there is no wires, just on the left side, 1st 2 on the top and 1 on the bottom left? I cannot jump the A and B Terminal because there isn't a A and B Terminal. How do you jump them? I did get the right harness from the exact car, the exact 1995 car, I have to go to the part dept at a gmc dealership. I did not replace the ecm. That why I wanted to check the ecm with a scanner to see if any problems, yet I cannot. It cannot communicate with the ecm. Let me know what else. Thx u.
