JG M4 S-System motor/gearbox disassembly

[infuriatednoodle]

Hey guys! Obviously being my first post here, I came for help regarding my JG M4 S-System 2010 w/mosfet. Recently the gun starting pooping out on me and eventually wouldnt fire and the motor made a noise as if it were dying. I am interested in looking at the trigger assembly in the gearbox but the problem is, is that I need to take out the motor from the grip to do that and I have absolutely no clue how to remove the wires from the motor on the top. I can post pics of it if it helps, but it looks like the wire is attached to the base of the motor and looks almost impossible to remove.

Help is greatly appreciated
