I'm so irritated at myself for screwing this up

. I did remove the red front "cover" but still couldn't get the wires to release. I didn't notice a slider but that would make much better sense. I'm irritated because the three wires I cut "depopulated" weren't supposed to be cut since I was in the wrong place. So I don't know what they were for but I'll reconnect them soon. The spot I should have used for the three wires for the camera was NOT populated so it would have been a breeze to finish this install properly. So...the three wires I thought were for the cargo camera were not for that, and the biggest issue is finding the metal pieces to go on the end of the wires, I had cut mine off to splice into the wrong three wires since I couldn't get them out. I'm just starting to look for them now. Just not sure what to call them. Do you know where I can order those?
