5.7l tbi connector. NEED HELP IDENTIFYING

[DKT5]

I was doing some maintenance and found this connector not sure if it's auxiliary or if even need it. Figured it wouldn't be a bad idea to post

Looks like your AC high pressure switch. It's on the back side of the compressor. Looks like it's right below your fingers in picture #2

How about the Knock Sensor down near the starter?

If you look close at the pigtail, where it disappears into the harness convoluted tubing, that connector would not reach there.

I'm just looking at the 1 wire connector. It looks like the KS one. Most A/C pressure connectors had 2 wires, except earlier ones that didn't have the "Recirc" button, which are NLA.

A/C HP sensors should look like this...
