just search champ, pics don't work but it'll tell you where its located

 

i saw that thread, and still could not find it. i was told that my motor was not the original but dont know what it came out of. inside my tb there is only 1 hole, not 2 so i was wondering since the later models did not have one, maybe that is what my motor came out of.. i have no clue

 

well one guy says its right under the throttle body, a few posts later somebody else claims that it is connected to the tb on newer b16, what is the code written on your engine block?
