Quick Help - Cabling in IS200

Troops - need a quick hand, installing tv into an IS200, anyone know the best route for cables from cabin to trunk?

It'd be great if someone could let me know before the rear seats get pulled etc!

Cheers - Mike

On a tundra there is enough room under the platic cap that hides the end of the carpet (thresh hold?)
I dunno if that goes all the way to the trunk, but its worth looking into.
