Default Jdm. Diagnostic plug in?

Is there one? or not. I'm getting a check engine light. And my cars in limp mode.

No, you have to find the black diagnostic plugs and connect them. Then count the number of flashes on the CEL.

Stock, the plugs are under the steering column.

Mine is swapped, and they are under the kick panel where the ecu is.

Your location may vary. . .

Little more info on it below. Codes are pretty standard on OBD1 Subaru stuff.

Actually there is one, on older models (pre 1999) there is a yellowish orange plug for the Subaru Select Monitor. Even US dealers will be able to diagnose it with the cartridge for the USDM Impreza of the same model year.

But as stated above you can also connect the single plug black or green diagnostic connectors and the CEL will flash the trouble code.

Evoscan and the SSM1 port is quite handy.
