The check engine light on my 1989 Subaru GL has been on for the last several years. The car runs fine (relatively), but I would like to know what is causing the light to come on. I have tried to read the codes from the ECU, which I was under the impression of being the box right behind my back passenger seat (accessed via the trunk). However, I can find no lights or buttons/wires to manipulate to obtain the codes, so I wanted to verify that I was looking in the right place for this particular model, and if so, what am I missing with this unit?

ECU Codes and reading

welcome to the board

nice to see more PAians

the link is from the repair manual on the page Header

here is another

As Glen says
the ECU is under the steering col.

You must remove the trim panel to see it

Your "read memory" connectors (white in color)
are under the hood by the
drivers side hood hinge.

You may have the wrong location. The ECU may be near the steering column mounted on the firewall.
