Has anyone removed the wiring harness that connects to the exterior of the headlamps? Any tips, I cant get it to budge.

 

I'm removing the headlamps. I have that issue with the broken adjusters, and its gotten so bad my headlights nearly point straight up in the air. So I'm going to attempt taking them apart and fixing the connectors, or if that doesn't work i'll be buying some new assemblys. I've got the bumper cover off and the headlamps out...other than this stuck harness. Any help appreciated.
