It will depend on whether yours is an OBD system or not. OBD (On Board Diagnostics), didn't start to become a legal requirement until 1996 but some companies were fitting them earlier than that. First check your steering column for the green style connector on the attached image. If there is none like that, use a torch and get your head into the Driver's side footwell. Your looking for the black style connector, (red circle), on the attached image. It will be at about the height of the driver's knees at the door side. They are sometimes tucked up under the dashboard, out of sight, possibly behind a small flap or cover.
I hope this helps.

SOURCE: my 1991 Subaru Legacy won't go into gear

Does it go into gear ok when its not running? When its running does it grind when you try to put it in gear? Does clutch feel firm or soft when you push it in? If you can shift all gears when its not running then its a clutch problem. If you can't than its a transmission problem. Is it a hydrolic clutch or mechanical? I can only guess and i won't do that, i need this info to help you.
