1989 Knock Sensor

I have a 1989 Chevy Suburban with a 5.7 and when i get into the gas and into passing gear the check engine light will come on. I did the old paperclip test on the OB1 port and the knock sensor code came up.....where is the knock sensor and how do I replace it????

I believe it is located on the passenger side of the block just in front of the starter. Should have one wire to it and then just screw it out.

alright will look at it tonight on my night off.......thx
