Gday all.
I have a VN Commodore dirt circuit car that uses an Ecotec with pink/blue plug PCM in a completely standalone VATS off condition.

My question is, seeing as the OBD port has been 'deleted' for some odd reason, which is the best way to wire one in for diagnostic reasons as well as for editing the tune when I upgrade to a NVRAM?

I gather it would be fairly straightforward and have a donor car to take a plug and wiring out of. Cheers

Just connect the battery pin, both ground pins to the car and ALDL (pin 9) to the computer. Look at the wiring diagram from the donor car that had that PCM service number to see which pin for ALDL which is also sometimes called "Serial Data".
