Cnstman Posted February 16, 2014 Report Share Posted February 16, 2014 Hello just bought and installed a V10 plug in in my usdm 2004 sti. Setup and initial fire went smooth. I did buy the expansion connector and I have a question on its functionality. The online manual and ivts help show 5 of the 8 pins have no function. The manual that came with the ecu had a function listed for all 8. Which is correct? We tried to wire a sensor to the white wire which is no function / anvolt11 (I think) and it did not work. Connected the same signal wire to a non used wire in the car harness and it worked perfect. Please let me know true functionality of this expansion connector. Also I entered my ecu and serial number in the forum. Will I be able to post outside the guess area soon? Thanks. Quote Link to comment Share on other sites More sharing options...
