How to fit a Rear View Camera to your Motorhome

By keef and annie hellinger, Sep 19 2014 05:50PM

This guide shows you how to fit one to a specific motorhome but in our humble opinion the principle is the same which ever home you fit it to.


Summary of steps


1. It’s a sensible precaution to test that the components are all functioning correctly before starting to install them. A fully charged 12V battery or suitable power supply will be required. Gentle flexing of the cable and joints should ensure that there are no breaks or snags.


2. Mark out the position of the camera bracket in the centre of reverse slope under the high-mounted stop lamp. Auto-Sleepers fit a horizontal metal reinforcement behind the inner skin of the Styrofoam panel and the hole should be above this. On this vehicle the reinforcement ended 40mm above the cupboard base, but this should be confirmed with a stud detector. Inside the rear cupboard, drill a 30mm diameter access hole through the inner insulation just above the camera bracket location.


3. Drill two 6mm diameter holes for the screw fixings, coat the camera bracket with mastic and temporarily secure with 6mm screws and nuts. Use large washers on the inner surface of the GRP panel. Use a ¼-inch M10 socket and universal drive to hold the nut. Tape the socket and any extension together to avoid dropping into the void. When the mastic has set, remove screws, coat the holes and washers with additional mastic and reassemble. This process gives a better seal because it allows the bracket to be secured before the mastic has set and then holds it while it sets.


4. Drill two 8mm diameter cable holes below the bracket. Fit the sleeve grommets to the cables, coat the holes and grommets with mastic and feed through the GRP panel and inner insulation. Wipe off excess mastic and arrange a loop in the cables to shed water. It may be easier to fit the sleeve grommets if they are split lengthwise and rejoined with superglue.


5. Remove left-side rear light and locate the harness feed hole. Drill a 19mm hole in left side of rear cupboard wall at level of 30mm hole.


6. Locate the left-rear light harness under the rear floor, remove the mastic from the feed hole through the floor and ensure that the hole is large enough to pass the cable plugs.?To avoid damaging the lighting harness it may be more convenient to cut it and pull it through the rear lamp feed hole. It can be rejoined later.


7. Moving to the front of the vehicle, remove the left fusebox cover and glovebox. To do this you need to remove the pocket above the fusebox to reveal a hidden fixing for the glovebox panel.


8. Inside the cab, remove the passenger wheelarch and side step trims and locate the large harness entry hole giving?access to the left side-member.


9. Feed the cable horizontally across the rear wall void from the 30mm hole to the 19mm hole made in step 5. Then vertically down to the rear light cable hole, through the floor, under the floor following the route of the rear light harness to the large grommet in the rear outer of the left side-member. Go along the interior of the left side-member, out the step harness entry hole, up the left wheelarch and into left fusebox area securing with tie wraps


10. The rear light hole and the 19mm hole are used as access holes and the cable is only temporarily looped through them. Electrician’s cable feed rods are strongly recommended for this process, though stiff wire may make a suitable alternative. Secure the cable to the access hole plugs with cable ties, feed the cable into the void and fit the plugs. These are purely precautionary measures in case cable recovery is required in the future.


11. Attach the mirror monitor to the existing mirror and route its cable tail to the left fusebox area via the headlining and left A-pillar trim. Secure the monitor control box to a blank area of the fusebox. Locate suitable feeds for the cameras and monitor.


12. Auto-Sleepers taps into the cigarette lighter feed from the fusebox for the rear step warning buzzer and this makes a suitable ignition-controlled source for the permanent camera. Connect with an inline fuse of 3-5A. A multi-terminal plug for the left rear light harness is located at the base of the A-pillar and the lead to the reversing light can be identified by cable colours and confirmed using a voltmeter. Connect the monitor AV2 switch wire to this lead. Fit the earth return to a suitable point. Connect all leads and loop any excess cable neatly in the left fusebox area.


13. Reconnect the rear light harness, if cut, and seal in a weatherproof junction box if external. Fill the floor access hole with a suitable non-setting mastic.


14. Tape the cable to the rear light harness and refit the rear light unit. Test that the system operates satisfactorily and adjust the camera angles using the adjustable brackets on the sides. When happy with the view, bolt the unit to its final position.
