Okay guys, on a Saturday no service depts open around here; we have the part, can't find the location for the following:

Where is the knock sensor located on a 1987 Chevy - 1 Ton pick up
with a 454 motor. It's a truck from California originally, and has an emission control # of 3Jn. That's all I can tell you, but we can't find old one is. Is it possible that it's located on passenger side on block, under exhaust manifold? Even our manual doesn't show. Closest town to ours is 30 miles away. Help Please!!!;-)
