Hi everyone,

New to the forum and I am needing some help. I have an 84 with a 22R. Prev owner made a lot of changes, it is a different motor, complete after market exhaust and I don't know what else. It won't pass smog and this weekend I noticed that there is no o2 sensor, the port on the manifold is plugged. My question is, where does the wire from the sensor go? I have searched many forums and googled it but I cannot find out where the wire from the sensor goes to. Thanks for any help.
