Need some ecu help!I have a OBD1 PR3?
 
i think i have an OBD1 PR3... the plugs don't fit my OBD0 car and they are way off... i did a little research and it shows the plugs like my pr3 as being OBD1. does this make sense?

bottom is PR3(?) ecu

I think that is an OBD1 ecu, my PR3 had clear and green plugs... Like the ones on the motor. B16A OBD0 = clear plugs B16A OBD1 = grey plugs

Yeah, that is definately not OBD 0 that is OBD 1.

ok thanks... if i get the right PW0 ecu will it plug into my existing harness? i know there is wiring differences but will the plugs fit?

Cynikal.Mindset 12-Mar-2004 03:18 PM
