1993 Buick LeSabre knock sensor

I need to know exactly how to locate the knock sensor in order to replace it. Is it directly under the throttle body (like the manual states) bolted into the engine on the upper left hand corner? I need to replace it in a hurry, but I can't find it. Do I need to remove the throttle body to get to it?

I am fairly certain the 93 is in the same place as my 94, if so, it is located more to the passenger side, front engine area, below the exhaust manifold, mounted on the block.
