2009 GMC Sierra SLE New Body Style Knock Sensor Issues

[red95mpower]

Let me first introduce myself. My name is Ryan. I have been lurking on these forums for a while. I truly appreciate the wealth of knowledge provided by the members. A big thank you from me.

 

I have to replace both knock sensors on my truck. It has a 5.3L. So far this is my parts list:

 

Part Number: 12589235 - Throttle body gasket

Part Number: 89060413 - Manifold Gaskets (sold in a set I assume)

Part Number: 12623730 - Knock sensors x 2

 

I can't seem to find a part number for the Knock sensor wire harness w/ the plugs. Does anyone have a part # for this part? I can only seem to find the part # for the models up the 2007.

 

Second question is: Am I missing any other parts to replace the knock sensors? I don't want to start the job and realize I missed something.

 

I thank you for you help in advance!!
