I had difficulty removing the starter solenoid wire plug with this clip as well (2014 Sierra). What prompted me to pull it is the vehicle suddenly would not crank (luckily was in my driveway). Battery new, voltage good, no click from solenoid. I crawled underneath and simply wiggled the solenoid wire at the plug, then it cranked fine. So I wanted to exercise the plug to wear off any oxidation. It was NOT obvious how to remove the plug, partly because is tight quarters there. But like the other plugs underhood, the key is to slide the red tab back, away fron the solenoid body and parallel to the wire. It would not budge with my finger so I went in with a flat blade stubby which fairly easily slid the tab back 1/4”. Then the plug pulled right out. if the no-crank happens again I will likely get a new plug, or I saw a video where the plug socket was ground off and a ring terminal crimped to the wire end, for securing under the stud nut. Like in the old days before obd2 and fancy plugs!
