I remember doing this and it was super easy. Yes I believe once you have eveything apart wires go nicely into cabin. If wires are giving you problems a small spray of silicone lubricant should do.
Figured it out...for what it's worth...took door panels off, had dash apart already especially near the kick corners, ran a long zip tie through the door side boot opening and found it peeking through a hole in the cabin front fender areas under the dash, grabbed it, taped wire leads to the zip tie, pulled zip tie back through door and there ya go!
