I'm sorry to dig up this old thread, but I was looking for the same thing and though searching I found this thread. Found the page for the '95 ECU and was just wondering if it would be the same pin locations for a '97 ECU. Looking to install this Defi heads-up unit and just want to make sure I'm splicing into the right wires for the rpm and speed signal.
