Managing the rear camera cable
Unlike the front of a car which is universally similar, there are vastly different types of car rear designs - consider the difference between sedans, hatchbacks and pickups for example. It's difficult to lay out a generic guide without specifically addressing each type, which is a tedious task and not very practical. Therefore, for this tip, we will focus on one type of car only: hatchbacks.
Start by connecting the cable to the mounted camera and work your way from here. This is to ensure that the cable will actually reach the camera once you're done, and also helps prevent excess cable from protruding near the camera.
Here we opted to mount the camera to the plastic panel instead of the rear windshield for a few reasons:
(A) Increased stealth level. Nothing on the windshield is better than a tiny object mounted on it.
(B) Avoid damages to the rear tint in the event that the camera mount needs to be removed.
(C) Less exposed wiring.
The plastic panel is perfect for routing and hiding the cable. It may help to remove the panel and make note of available space. Utilize existing latches to secure the cable, or use cable ties. Run the cable behind the panel until directly aligned with the side of the car interior where the trims are.
Stuff the cable into the small gap between two trims. Once the entire length of the gap is stuffed, push the cable so that it rests fully behind the trims and does not cause the trim to bulge. Leave just enough cable length to the rear door to allow normal operations, you don't want an opened door to jerk the cable right off the camera. Nothing should be visible from the gap, it should appear exactly as before (save for a cable protruding from each end at this stage).
Now to take care of the protruding end that will eventually connect to the main console. We strongly recommend routing along the floor instead of the roof so that you don't risk hampering side airbags (if applicable).
The trims are all interlocked with ample space behind for wires, so simply guide the cable down to the next trim. Pry away the rubber seal strip to expose the edges of the trims.
Continue running the cable along the trim down to the floor. Remove the scuff plate and route the cable in the cavity beneath it. Repeat for the front scuff plate, and the rear cable is ready to plug into the console! There should be an abundant amount of cable left, leave enough to plug into the console then stow the rest behind the bottom dashboard cover.
