My tail light on my 2016 Trail was broken in an accident so I'm trying to replace it. I removed the damaged one from the vehicle and now have to remove the wire harness and install it in the new tail light. Problem is I can't figure how to take off this white clip (see pic). Doesn't seem to be a tab or something you push to slide it up and off. I've tried pulling it straight out but it didn't budge, even with some force, and I'm worried about breaking the part.
Can anyone who's done this help?
