2007 Tahoe, which knock sensor to use?

Hey Fellas,

I need to replace one of the knock sensors on my 2007 Tahoe 5.3L (code P0330, and P0332). Trouble is, the part finder on amazon and advance are showing me a strange looking type of knock sensor I've never seen before (See this link (http://www.amazon.com/ACDelco-213-1576-Original-Equipment-Detonation/dp/B000C9GGBG/ref=sr_1_1?s=automotive&ie=UTF8&qid=1436877925&vehicle=2007-47-499-96--9-6-8-8149--1-1-145-104-11-0&sr=1-1&ymm=2007%3Achevrolet%3Atahoe)) This sensor has an appearance similar to the outer end of a centerlink.

The repair guides I've seen all show using the same type of knock sensor that's been in trucks for the last 20 years (saucer type that threads into the block with a white plastic protrusion for the wire).

Which one is the correct type?

Yours should use the type shown in the link you provided.

Thanks, are these still located in wells underneath the intake plenum like the GMT800 5.3L?

I believed your's are on the sides of the block. One on each side.
