Default OEM Camera in 2012 Impreza

I bought a 2012 Impreza in December and wanted to install the OEM camera since the 4.3" non-navi display has (what appears to be ) software for a camera. I picked up a used OEM Forester camera (Clarion) for pennies and was going to install it until I realized that the factory stereo wasn't going to cut it and installed a Pioneer P4400BH head unit.

The pioneer is a dual din video unit that supports a rear view camera and I've decided to put one in even though the Impreza has great visibility compared to other vehicles. The easiest solution would be to install one of the various bolt on units off of ebay or your retailer of choice. I've decided to use the OEM camera since it will look more original and I already have one. I'm sharing this info in case others have the same thought. Remember that the upcoming XV has a rear view camera so parts may become readily available in the coming months.

The first step was to pull the rear panels. No factory wiring is present. The good news is that there is a cutout in the steel hatch behind the plastic panel above the license plate. I believe it will fit the camera but it appears that I'll have to Dremel out a hole in the plastic panel located above the license plate. There are markings in the plastic panel where a camera would be installed but I'm not sure why they are there.

Wiring and power supply are the next challenges. The OEM camera requires a 6V power supply so I've ordered an inexpensive 12v to 6v converter off of ebay. Another option would be to use a 7806 transistor. For a few bucks more, you get wires and probably the same exact transistor inside of a plastic housing.

I wanted to confirm that my used camera worked before I installed everything so I did a bench test with a 6v power supply and hooked the camera up to a tv. I couldn't find wiring diagrams for the camera so I guessed and gave it a try. It worked!

Red +6v
Black -6v
Yellow Video signal
White Video shield

If anybody has other information on the wiring, please reply. I'll continue to add to this thread as I complete the project. Waiting for the power supply at this time.

Glad to see someone else working on this! Check out my thread on the Forester forums:
2011 OEM rear view camera / CP635U1 HU research
(that talks about the similar HU with 4.3" screen found in Foresters, but the camera signals are the same).

I'm very interested to find out how much current the OEM camera draws. It would be really nice to be able to use the smaller 78L06.

The factory harness has 4 wires: camera video, power, camera detect, and an outer shield. The latter provides the ground for both the video signal from the camera and power supply to the camera. On every Subaru wiring diagram I've seen, the factory harness does not include a wire on the HU's camera power ground lead.

The camera connects the detect line to ground (so the OEM HU can tell when the camera has been installed). The factory harness can't do that, since it is often pre-wired in cars that ship without the camera. But if you were adding the camera to an OEM HU in a non pre-wired car, you can simply connect the HU's detect pin to chassis ground right there at the HU (so you could run one less wire from the HU to the camera).

Looking forward to your testing, I also want to use the factory forester camera, on my 2012 forester, with a Pioneer X930BT HU.

How did you bench test your camera? Did you splice the wires and connected them in a RCA cable and then your TV? Was it in color, or BW?

Looking forward to more of your testing, I want to use the OEM factory camera as well on my forester.

I cut the original plug off since I figured it would be difficult to find the matching plug and didn't have original camera wires in the rear door anyway. Then I just hooked up a 6vdc power supply and wired in a temporary rca plug so I could hook it up to a tv. The picture was color and looked decent on a 17" tv. Just an fyi...the label on the camera should be "up" for the correct orientation.

Would it be possible to give more details on how you did the wiring? This is exactly what I want to do, and I have no knowledge in doing so, but can and I am determine to do it!

Post up pictures and how you did it?

Thanks,
JP

Can you also post up which voltage reducer you got? So basically, you need to wire the 6v red wire to the reducer and the black wire to the ground?

How about the video signal?

Thanks, and really looking forward to more info!

Still trying to find time. It will happen, just not sure when.
