Running rear view camera cable to the back?

Upgraded my dash cam to one that includes a rear view camera that would mount on the hatch glass. Poking around it seems to be a shitshow on getting that cable to the back, with the curtain airbags, plastic trim, stiff headliner, etc.

Anybody have a how-to on this project? I searched multiple terms but came up blank.

 

Much simpler than I thought, for anyone looking to do this. The only challenges are getting the camera wire past the B pillar, then to the back corner. Pop a few pieces of interior trim away from their mounting points, and use a straightened coat hanger to fish it through. Probably took me no longer than 30 minutes.

 

Follow the factory wiring and washer hose down the passenger side door sill.

 

I went up top through the headliner area.

 

Have any of you taken pics of the process?
I'm one of those who learns better when I can see something than when I can only read about it.

 

Sorry, I did not. Any questions, though, just ask.

 

Thank you.
Once I get off my tail and get my camera ordered, I'll be asking more about the process.

 

I used plastic pry bars and slid it under the head liner. I attached my camera directly to the plastic button that holds up the head liner. You can buy pre made pieces on Etsy that slide under the button.

 

I am getting ready to do this when the weather warms up a little. Have a 3 channel VanTrue dash cam.

Are there any videos or pics on this procedure ... anywhere ??

 

That's exactly how I did it.
