[V8] "Major Surging"

[BBlake1055 at aol.com]

Ok now that I have totally screwed it up.  After 30 minutes of going back and forth with rust blaster I got the O2 sensor out but screwed up the black wire connection at the head.  What does the black wire do and can I splice into it somewhere?  I broke the connector off right at the connecting block (didn't realize it was a "slip on" connector.

Now I know why I stopped working on my own cars years ago!!!!

Also, anybody know what thread the O2 sensor is?  I need to clean the threads up a little - part of the O2 sensor threads are still in the X-pipe.
