Electrical Connections

  1. Check that all electrical connections are free of corrosion and securely attached. Check DME ground wire on engine flange and on clutch housing near speed and reference mark sensors. Be sure connections have good contact and are tight.
  2. Particularly check 9-pin connector above brake booster, 4-pin connector on air flow sensor, 3-pin connector on throttle switch, 35-pin connector on control unit, 2-pin connector at temperature sensor, 1-pin connector for oxygen sensor (on firewall above flywheel sensors), and two 3-pin connectors for flywheel sensors (attached to No. 4 cylinder intake manifold).
    NOTE: Control unit connector is held in place by a catch. Push catch to the right and pull off plug with a downward motion.
  3. In addition, on California vehicles, check 2-pin connector for oxygen sensor heating element.
