Rear window mounted dashcam

[UrbanHiker]

I’ve just purchased a Nextbase Dashcam that came with a wired rear camera that is deigned to fix onto the rear window.
The front facing camera I installed without any issues and is working fine, however the rear mounted camera has me scratching my head somewhat…
So I had planned on running the cable from the front camera to the rear of the van via the headlining, a pillar, door trim, down the b pillar and behind the fitted units in my leisure drive conversion all the way to the rear doors, then I’ve hit a problem…how do I get the cable to run onto the rear barn doors?
I had thought about running it via the rubber cable trunking that connects the barn doors to the body, but this seems to terminate in a void between the inner and outer skin of the van. I’ve taken the rear light assembly off but can’t see any way of accessing this from inside the rear of the van.
This has got me seriously puzzled.
If anyone has fitted a rear mounted camera on the window to their barn doors, can you please give me some advice on how to route the connecting cable?
Thanks in advance, John

Before my dashcam broke, I had the rear camera mounted on the body side of the door opening and got a good view angle pointed through one of the barn door windows. Just made a bracket and used rubber well nuts to fix into the existing punched holes in the metalwork.

Thanks for suggesting this as an alternative to mounting directly on the barn door window, it would save a whole heap of hassle as I can get the cable to this location without too much trouble. I’ll have a little experiment with making a suitable mount for it in my workshop over the next few days. Thanks again for the reply and advice

the factory cabling goes up the C pillar from the rear light units - there's a hole further up inside the van that allows access but is usually carpeted over when vans are lined. You'd be able to drop a cable down from the roof lining though.
