You can use the injector harness and o2 harness from a 87-93. As for any other harness no, certain years have certain harnesses

You will need a 1991-mid 92 computer harness
Engine harness is the same from 86-93
o2 harness is different from 88-90 than 91-93, also auto and manual transmission specific.
let me know when ready and I can help you out.

If it's a 5 speed the only way to be sure you don't toast your EEC is to test for power at pin 46 on the EEC harness. Do that to make sure you don't fry your EEC. As stated above auto/5speed harnesses are different, & 5 speed harnesses vary by year, so be careful.

You should just need the short jumper harness that runs from the connector on computer harness by the starter solenoid to the A/C compressor itself.
If you don't have this, its what you need,
I have many of these and I will give you one if needed.

I know the differences in the harnesses and will help anyone in need to either confirm they have the correct harness or get them the one they need for their application.
