Door harness cover replacement

How can this be done in a MKII? The rubber cover that protects the wires that go from the car to the door is torn on both sides in my 2. I do not see any way to unplug the wires. Do they unplug under the dash? There has got to be a way to do this since there is no way they could have built a rubber part around a wire harness at the factory. HELP!
