Alright, I looked at my buddies and his is deff. in the exhaust manifold. My car must have the Civic downpipe & the Integra exhaust manifold. Looks like I have to hit up the junk yard to find one or the other. Now, does anyone know what color wires for the 02 sensor are? There are a few plugs that don't seem to go to anything. One is pretty long & would easily reach the downpipe location. I don't think the other one's will reach the exhaust manifold.
