Can anyone tell me what the difference is between a 3 plug ECU and a 4 plug ECU on a 96 WRX?

In respect to what.

4 plug MY92 to MY96

3 plug MY97-MY98

Different 3 plug MY99 -

Bound to be slight overlap due to registration issues.

Bob Rawle - Spot on ... well said.

Thanks Bob. That answers my question. I believe that the new models come out in Japan late in the year. So most 96 cars will have a 4 plug ECU. Some late 96 cars might have a 3 plug ECU. Is this correct?

Careful cos I think they changed in October.

Could be either cos seat belts could have been manufactured well before the car.

Bob

MY96 is from late '95 to '96
My97 from late '96 to '97

My car 1st registered Dec '95 and is MY96

And there's me thinking all along my car was called a MY96....but my seat belt label says it's a Sept 96...so I guess it's referenced as a MY97....

hmm....!!
