Oh I didn't even think about how they got it out, because when we dropped the engine out of my firebird we dropped it out the bottom because it was easier. Alright well that makes me feel a little better now, thanks guys for the fast reply. Lucky for me I saw a few knock sensors with the harness on ebay for sale, I am a newbie with the tuning thing as well. I have been leaning a lot from this site though, so hopefully I will know a little more now.
