1. Install the 10-way gray connector to the inside of the firewall using the double push-pin fastener
included in the connector.
2. Install the C100 34-way connector to the firewall bracket like stock.
3. Route the harness over the AC Liquid line and around to the PCM/Computer. You can reuse the
factory zip ties to fasten the harness to the washer bottle tray
4. Plug the harness into the AEV PCM and then into the AC Pressure Transducer.
5. Install the AEV 4-way Pigtail Harness into the PCM/Computer connector C3 (body side—white)
connector by releasing the terminal lock inside the connector (red slide.) Insert a very small allen
wrench or similar tool into the backside of the cavities specified on the pigtail wires and with a
small amount of force, break off the small plastic studs and poke them through the front of the
connector. You may need a small needle nose pliers to remove the plastic studs from the connec-
tor. Once the cavities are clear, insert the wires until the terminal has a definite “click” into posi-
tion. Once all the wires are inserted, activate the terminal lock and plug C3 into place.
