does anyone know of a good site for wire diagrams for hondas . i am trying to wire a secondary 02 sensor into the harness for sensor input,ground,and heater curcuit, the reason i am doing this is because i had a d17a1 and swaped for a d17a2,the d17a2 harness does not have the two 02 sensors on it like the a1 harness, just the primary sensor,so i need to wire the secondary 02 sensor into the harness.i just need wire diagrams.

I have never been to a library that offered automotive manuals and I hope I never find such a place.

The PDF service manual should have a diagram of that circuit, my paper one does: https://www.civicforums.com/forums/1...e-updated.html

I have a stock A2 in my EX and I have a secondary sensor. Are you sure you have an A2 harness?

Been there, done that. They never have the one you need.
