Camera Input Information
If you haven't already, see important information about the head unit's camera input on this page:
In particular, see the section "Test your camera before installing!"
These instructions are for my "plug-and-play" 16-pin camera harnesses.
Camera Power Wire
The 6 Volt camera power lead on my harness is RED/WHITE (mostly RED with a WHITE stripe). This lead provides a 6 Volt power supply to the camera. On older versions of my harnesses, the stripe is YELLOW, and I may have also labeled that "6V to CAM".
If your camera will work from 6 Volts, connect the camera's positive power wire to my 6V lead.
For a camera that requires more than 6V, you can use the 6V lead to control a small relay. See more information and diagram on my Camera Input Information page. Or if you don't want to bother with a relay, insulate the end of my 6V lead. In both cases, you would have to use your car's 12V Accessory power for the camera's power.
On BRZ, FR-S, and 86 models, +12V ACC power is available from the factory "Option Connector" harness. I can supply a harness which fits that harness (e-mail me for details). Sorry, Impreza, Forester, and Crosstrek models do not have that.
Connect the camera's ground lead to chassis ground (e.g., to a screw or bolt located on a good, clean, bare metal contact point nearby). If the camera's ground lead is at the HU end of its cable, you may connect the camera's ground lead to the CGND lead (BLACK) on my 16-pin harness.
Install Camera Harness
If your car has an existing factory harness with a 16-pin plug, unplug that harness from your OEM HU and replace with my 16-pin harness.
If you ordered my harness with the parking brake pass-through option (with the additional 16-pin socket), plug your car's factory harness into that socket. I recommend wrapping the pair with some self-adhesive foam tape and/or tying that junction onto another harness, to prevent rattling.
If you ordered my harness with a parking brake bypass (a wire looped back into the 16-pin plug), tie or tape down the factory harness that you unplugged, to prevent rattling.
On an older version of my harness with the 'bypass' option, the parking brake lead is just a straight wire with a "fork" terminal at the end. If your harness has this, connect the terminal to chassis ground (via a screw on the rear or side of the HU). Tie or tape down the factory 16-pin harness that you unplugged, to prevent rattling.
Test the rear camera function before you reinstall the HU and reassemble your dash. Tip: You must turn your ignition key to the "ON" position for the reverse lights circuit to work. You do not need to crank the engine, though.
Adjust Parking Guide Lines
On North American Fujitsu Ten HUs, the guide lines cannot be disabled, but they can be adjusted to suite your camera's position and view angle. There is a menu option within the HU's Diagnostics mode. To access the menu:
If you start by pressing MAP, you'll enter a completely different tree of menus, pictured in this post. You can't reach one set of menus from the other. But both do include screens where you can check the reverse gear signal (handy for a car where you don't know whether the reverse signal is connected, as is the case on FR-S models).
On Australian models, you can see the guide lines on the Camera Setting screen, but they are not displayed during normal operation. I haven't heard from anyone who has discovered a way to enable the guide lines on those models (or to disable them on North American models).
