Thank you

I haven't taken a close look at the CX9's, but most modern day cars now have a molex connector from the cabin to the door Video (start at about 2:40 into the video). Actually, this video gives you a pretty good overview of what's required these days; it's quite involved.

It used to be so simple back in the day because the car manufacturer's used to run a few tiny wires through this booted passage so you used to be able to pass a train through here. Not any more.

Door panel removal video if you decide to continue, or are just curious about it.
