harness connectors

How to remove stubborn harness connectors? Im having a bit of trouble disconnecting the one at the front near the battery tray for light control I believe.


Its the 2nd one (red) closest to the bumper.

Any help is good help, as I’d like to not butcher this harness lol

flat head, pliers, lube, whatever it takes.

Yea, I’ve been trying different methods, but never thought about using a flat head.

Thnx sidewayz
