Ice Door Kit

The ice door on my dispenser is broken. I ordered an Ice Door Kit to fix it, part number 8201649. I am having issues trying to get the control board bracket removed so that I can get behind it and install the new ice door. I have disconnected the harnesses but the wires that come out of the door itself into the bracket don’t seem to disconnect so that I can remove this white bracket. Any help with this is appreciated.
