GeneralDisorder Posted November 8, 2010 Share Posted November 8, 2010 You can trace which pin on the ECU is for the read memory function - just go to my SPFI conversion page and download the PDF factory service manual at the bottom - it has the ECU pin-out for both SPFI and MPFI (I think). The pin is one half of the connector pair - the other half is just a ground wire. You can make a new pair of connectors by just crimping some male/female spades on - one to the ECU read memory pin and another to a ground wire with a ring terminal on the other end and bolted to a conveient ground under the dash. http://home.comcast.net/~trilinear/EA81_SPFI.html Quote Link to comment Share on other sites More sharing options...
zacyork Posted November 8, 2010 Author Share Posted November 8, 2010 i figured it was going to be a ground wire. thank you for the reply. having the pin number on the ecu will be handy indeed. Quote Link to comment Share on other sites More sharing options...
