I have a 92 Typhoon with a lq4 and 4l80e in it. I have a custom harness done by current wiring performance. I have found that pin 20 on the red engine harness is grounded. I have no idea if that is right or i have a harness is grounding some where. Any incite to would help i know it is for the vss low. i have it unplugged and it still blows the fuse. so I'm thinking either grounding wire or bad ecu maybe. thanks for your time
