im in the same boat. trying to figure out how to wire a wideband into the ecu. im waiting for a honda tech i know to send me a diagram tomorrow. i'll ask him for the pinout as well. do you need a specific connector or all three?Can anyone send me a diagram or link to the ECU pinout for a 2015 Civic SI manual trans.
8th gen pinout is easy to find. 9th gen is oddly difficult.
No. Their diagram shows pin 11 pin 40 in my picture. Their diagram shows the terminal side not the wire side so it's backwards. But the first and last rows are larger terminals so they number them 1 through 20 then the small ones in the middle are 21 through 49.And their diagram has it starting at pin 39 on the row instead of 40?
