11Budlite Posted June 27, 2009 Share Posted June 27, 2009 I wanted to start a separate thread from Kyle's "Car for Sale" to try to ID the stock ECU/induction that used to be in my Birkin. The date on the ECU is 5/24/96. Per the factory manual, pins #13, 15, and 16 go to a data link connector. Looking at the harness connector I have, those 3 pins were clearly used at one time (the sealing has been pierced) but no longer have wires/pins going to them. The harness also has connectors for both front and rear O2 sensors. Is there any way to know for sure if this ECU is OBDII? Here's a photo of the label on the ECU: Link to comment Share on other sites More sharing options...
scannon Posted June 27, 2009 Share Posted June 27, 2009 All cars starting in 1996 were required to be OBDII. A quick google search on obdii turned up this page and many others with lots of info. http://www.obdii.com Link to comment Share on other sites More sharing options...
11Budlite Posted June 28, 2009 Author Share Posted June 28, 2009 Thanks Skip. The data link connector diagram from the factory manual matches the Ford info from your OBDII link so it could be hooked up if I got a connector from a junk yard. The only other potential problems might be codes that could result from the other items not used in the Birkin installation. Thankfully CT doesn't require emission testing on component cars!

slomove Posted June 28, 2009 Share Posted June 28, 2009 FWIW, on the Birkin Owners list there is a file Fordv11.zip in the file section that a previous Birkin owner collected with a bunch of Ford ECU wiring info. Not sure if it is relevant for the topic here..... Gert Link to comment Share on other sites More sharing options...
JohnK Posted July 4, 2009 Share Posted July 4, 2009 Your Ford dealer should be helpful here. I got very good info from mine. I think that when the ECU went from EEC-IV to EEC-V and/or around 1996, there was a switch to OBD-II industry-wide. The Ford factory manual is a gold mine, but it may give you more info than you'd like to know. As for identifying your ECU, the largest font on the label is the identifier, and is called the "catch code". Yours is "DJK5". There can be very, very many of these for what seems to be one model. Each ECU/Catch Code has tables in it that describe the properties of each of the sensors/effectors that the engine uses and these can change mid-year, along with the connector design. For example, I found less-than-good running due to swapping out air inlet temperature sensors, so effort spent making sure that everything is absolutely stock pays off. I still find that design-wise, the Ford system is by far the most advanced in the market. Link to comment Share on other sites More sharing options...
