Turn the base upside down

Remove the rubber feet to expose the screws

Unscrew four corners

Turn the unit right side up

Pull the blue case up and off

Pull the yellow face plate up and off

Lay it face down next to the base to access the inside of the connector

Note the wire colors before de-soldering

White pair on the left

Black pair on the right

Green on the bottom

Bridge the Bottom and Top (Shield?)  with a 1M resistor

To remove the connector:

Plug in the soldering iron cable

Use pliers to squeeze the tabs

Wiggle from the tab side and pull gently from the cable side

Push in the new connector

Unscrew the PCB

Screw on the connector's locking nut

Replace the PCB

Heat-shrink over the 1M resistor (910k...close enough)

Re-solder the connections onto their corresponding pins

(This is when I realized...  the shield of this connector does not have a dedicated pin. So in this configuration the resistor is rendered useless. One day I'll move the resistor from the center pin to the connector casing directly.....maybe)

Use a small flat screwdriver to pry up the black tab

Pull the black sleeve towards the cable to reveal the innards
