where is the self test connector? and the MCU? are they in the car, or in the engine bay? I've just buy a code reader at walt-mart today, and I have like, 3 MCU connector at the same place... so I'm not really sure which one I should take ...
It's near the driver's side strut tower...the one on my 91 is actually attached to the back of the strut tower. The one on my SVO is to the front of the tower.
It's the ONLY plug that will fit the code reader. It's a big goofy shaped plug and then a small single wire plug.
