Leave the plastic, it stops dust and moisture from wrecking your door trim, The easiest way to get it out of the way is to cut the black goo with a knife while pulling the plastic away. you only need the green and blue wires. you can hook them up to the factory door lock module next to the glove box or next to the steering column on series two, to run the wires through the door you need to undo the 10mm bolt in the connector in the door jam. then un clip the connector from the car side and pull it out all the way and stretch it so you can plug them together out of the mounting. then pull the rubbers back and carefully drill a hole through the guts and that will allow you to run 2 wires through for the motor.The attached pic gives you an idea of how to mount the motor, hope this helps, -Danny :wizard:
