engine managment light on my 1995 V2 WRX keeps lighting up when cruising around 100mph.

has it got ODB2 or 1? ive got a little ODB2 tool to pull the fault codes out, but cant find the diagnostics connector? where is it??

 

1999-2000ish i think.

On yours there is a manual way to check Scoobypedia | Trusted knowledge for everything Subaru | Scoobypedia / Scoobypedia under the ecu heading

 

Neither. It has a Subaru Select Monitor 1 port.

That's going to do you no good at all unfortunately. You can read fault codes straight off the CEL - search for "black plugs".

For what it's worth, UK and jap market Imprezas became OBD2 compliant with the introduction of the bugeye. USA got it with the late GC's
