VS Commodore manual/auto conversion wiring step by step instruction.

[Beno1982]

On the manual gearbox there are two connectors, one for the reverse lights and the other for the speed sensor.

Reverse switch​

Connected to the auto shifter is a white plug with four wires connected to it the grey and grey/black wires are for the neutral safety switch, they need to be shorted together to allow the car to start. The other two wires on this connector are pink and green, these wires are for the reverse lights and need to be run to the T5 Reverse Switch.

Speed Sensor​

[/B
Now on the speed sensor to get this working you will need three things:

• Positive
• Negative
• Signal wire to the dash

The signal wire is the Purple/White cable this has to be extended over to just above the ECU where you will also find a purple/white wire on a plug leading from the computer up into the dash, this is the wire you need to cut and connect your extended wire.Only cut this wire on the body harness side leave the ECU side, and join the new purple and white wire to the purple and white wire that leads to the dash/speedo.

To avoid Engine light issues you will also need to solder in another wire to this purple and white signal wire which is to lead into D2 on the Manual ECU

The second wire on the speed sensor is Pink/Blue this wire is your positive. This wire should be run through a fuse into a power output, ie. stereo, key on power.

The third wire is your negative, this is the black/white wire and it needs to be earthed out onto the body somewhere.

That appears to be a comprehensive solution for those doing the swap - good one.

vs

i take it this was with the manuel ecu is is it still able with the auto ecu?

 

[Beno1982]

Yes definately will get best results with manual ECU.

 

[gregphillips]

would this work with a v8 conversion too?

 

[Beno1982]

i not to sure but. I could be wrong and hopefully someone can correct me if i am but i don't believe there would be.
