[dgms240]

if any of you has one of these ecu's i need a pic of the serial cable that comes out of it, with the plastic cover removed. my computer kept telling me to reconnect when i tried to hook it up, i checked the pins on the serial cable and only 2 of the wires were connected. i need to find which pins the others go to so i can fix the plug and get my car tuned! thanks!
