2015 F150. I bought a back up camera.

What is the best way to run the wire bundle inside the truck?

There is a grommet where the hood release cable goes through the firewall but it is super tight and I don't want to wreck it trying modify the grommet in that area.

I could run the wire up from underneath the truck into the cabin at the drivers side a pillar area. It would run up and over the weatherstripping. With that method I worry about getting noise or water in the cabin.

What are my other options?

Thanks.
