While the Vantrue Mirror Cam 3 comes with two mounting options for the rear camera, we installed it on the rear windshield for this Hyundai Santa Fe. Plug the rear camera connecting wire into the front unit.
Route the rear camera connecting wire through the A, B and C pillars.Carefully remove the side weatherstrip from the front and rear doors. Use the trim removal tool to lift the pillar trim slightly, and remove any mounting clips under the pillar by gently pulling the panel cover.
Remember, don’t just stuff the cable under the rubber seal because it will create a little gap that might prevent the door from sealing properly - you will get wind noise, or worse, water can seep into the car.
Mounting the rear camera in a vehicle with a rear liftgate does require a few extra steps, and the best way to run the cable is to go through the hoses between the chassis and liftgate. Typically, there are 1 or 2 hoses that connect to the liftgate, and it's best to give them a squeeze to check which one has more wiggle room before attempting to run the wire. You can also use a long zip tie, a coat hanger, or any variation of a long wire to guide the front-to-rear cable through the headliner and the rear hatch grommet before connecting to the rear camera.
