You could take the easy way out and buy a new harness....
You could take the hard way out and rewire it....

 

P07 on a Y8, how many CELs? (your CEL has to be on, if it isn't make sure the bulb lights up when you first turn on the ignition)

other than that...

that's about your only route. Either way it's not going to be pain free.

 

If you search I know theres a list of all pinouts, Ithink you need to search for obd-1 ecu pinouts or somethin like that.

 

This might help:

Here is vtec wiring:

 

your car doesnt have iabs so it doesnt matter that that wire is disconnected
