Trying to install my older avic 110 into my 2002 accord so I need to tap into the vehicle speed sensor. I have looked all over looking at pin outs of the ecm and dont understand why they dont match up. Iv herd that its located in connector A but I only see A19 engine speed pulse thats even close. From all the pinout prints that I got it should be located in connector C at C23 blue and white wire but Their is a yellow green wire at that location? Can someone tell me what im doing wrong.

This is a good site. It will tell you all the wiring you'll need.

 

I still dont see anything that can help me out. Does anyone know why the pin outs dont match.

 

Auto or manual?
