Attach your old wire B7 to that pin, then cut off the old plug from the esc module and attach the knock sensor wire (usally blue) to the signal wire (usally yellow with a stripe, I think red) This will connect the knock sensor to the pcm. You will also need to get the correct knock sensor. Get one for a 95 1500 with a 350 for a auto trans. The connector on it should be black, not white.
