Excuseme tgates, where did you exactly find the knock sensor. I still trying to find it.
I found the fan switch (passenger side next to cylinder 8) I know how it looks, I checked on Google images. We have the same engine.
Thank you!

For what it's worth, Chiltons shows three devices on the passenger side of the 91-92 5.0 and 5.7L TPI engines. The knock sensor is shown in the middle, between the fan temp switch to the rear, and the A/C fan switch toward the front. The knock sensor has a single dark blue wire.

In the later 5.7L engine (LT1) the knock sensor is screwed into the block drain hole near the motor mount. It looks like this:

Hi Fred, I want to thank you for your help, I found the knock sensor this past Saturday while working in the camaro. Now I have to find the cable for the Cooling Fan Switch, the connector was missing and there is a white cable hanging around, just in case you now let me know and again thanks you.
