So i was trying to replace the BEM today in my EF Fairmont and I unplugged the wires at the front without a problem but when I try unplugging the wires at the rear of the module I can't seem to get them out. There are two clips and both are stiff and only move slightly, I use a lot of force but it only seems to pull the module with the wires. Is there some sort of trick to removing the wires?

EDIT: All fixed pliers and some force got it out.
