you mean the inside door panel? thats easy to get off, find the few screws, then just pop the clips holding it down, start at a bottom corner.

once the panel is loose, pull the door handle so it will slide out the panel, then lift up, if you have lights on your door go slow, un hook the wires to the lights, and window switches and so on.

now that the panel is off all the wires are easy to see and un hook.

do the same to the new door, remove its wires, then swap the wires over, window switches locks and so on as needed. this way you can also keep your factory door panel, as it should match better too. unless your is beat up good.

all thats in there is the wires to the lock actuator, the power window regulator, the master window switch power mirror wire, and if you have door lights one more plug.
