Anyone know what wire on the ECU conector is the secondary O2 sensor signal? Or at least wich of the 3 conectors that goto the ECU it's clustored with (ie, the big gray, blue, or little gray one)? This is for a 1999 prelude.

Thanks a bunch to anyone who might actually know

 

Bump 1 time just in case someone has an ECU connector pin out

 

its in the little gray plug, the wire is the second in from the left on the bottem... i dont have the pin out scanned but ill try to get to it soon so i can give you a pic.

 

Thanks, that helps me out big time... Now I just hope the 97 prelude is the same as the 99 prelude on the pin outs
