These install instructions are for the 2007 hatchback 5 speed aveo. I will check to see if it is the same for previous years, but it must be the 5 speed hatch. Automatic tranny hatches have a different ecu pinout.
Ok, the powertrain control module is under the hood, on the drivers side strut tower. There will be 2 plugs. One on top with a grey connector and one on bottom with a black connector. These are what we will be working with for the install.
Remove battery cables from battery
Now, for both conectors, on the front of the connectors, there is a little clip that will release a lever which will pop the connector off the ECU. Once this is done, you need to remove the black cover that covers the wires, there are clips on both sides. This will allow you to see the pins and wires on top of the connector. Next cut the zip tie holding the wires together, and remove the electrical tape holding the wires together.
You are now ready to install the safcII
On the top grey connector, you will need to connect these wires:
-Purple knock signal wire from afc goes to pin 22 light blue
-gray throttle signal wires from afc goes to pin 41 white
-find the light blue pin 28 MAP sensor signal wire. You are going to cut this wire. You will connect the yellow wire from the afc to the ECU side of the cut wire, and the white wire to the sensor side of the wire.
On the bottom black conector, you will need to connect this wire:
-green tach signal wire from afc goes to grey wire pin 41
Now all you have to do is connect the brown and black wire to a ground, and the red wire to an accessory power source. The other wires (blue, pink and orange), just tape off and dont worry about them, they are for other vehicles. If you have any questions, or need clarification feel free to ask. Thanks.
