I got a good deal on a 2009 G37 rear view camera for only $20. I am going to install this right above my license plate, under the Nissan emblem. Now this camera does not have the usual male/female connections like the ones on ebay. It has 4 wires going into a 4 Pin connector (black/red/white/yellow). I know i need three wires for install: The black & red for + & -and a wire to connect to the green reverse wire in the car. Does anyone know what wire is the reverse wire on the camera (the yellow or the white)? Also what is the extra wire? Can i just not connect that wire? When i installed my sunshade i also had an extra wire that did not need to be connected. I looked through the 2009 FSM, but it is not as clear with the wiring as the earlier models. Here is the link to the 2009 G37 FSM: http://www.nicoclub.com/FSM/G37/Coupe/2009/AV.pdf. Here are the pics:







I am going to cut the 4 pin connector off and then splice the necessary wires together. Any input or suggestions are appreciated.

 

The camera control unit (the part where the camera plugs into) is what turns on the camera when it see a reverse signal either thru the shifter or a reverse light.

Since you only have the camera, for your custom install,

terminal #1 Red----- power (+)
terminal #2 white--- ground
terminal #3 Yellow-- Camera Image
terminal #4 shield--- Camera Shielding

1. hook up power and ground to your reverse lights so the camera powers up whenever the reverse lights are on.
2. get a rca video cable, cut off one end and wire the lead for the center pin to the yellow wire and the shield wire to the other wire

 

The video output is 2 wires and then you need +\- and the last would be the reverse

 

I was looking at the control box section in the FSM for awhile trying to see if i needed that in order to get this to work. I was figuring that's the wire set-up i need but just wanted to double check before i do the install. Better to have confirmation from someone before i get into this. This should be as straight forward as the sunshade install. Thanks for the info. I will post pics of install when i am done.

 

Theres only 4 wires. Since there is no dedicated reverse wire, i was going to just wire the + & - to the reverse lights & then the yellow & white to HU. This would give the effect of only turning on when i put car in reverse. Correct me if i'm wrong.

 

the wiring pinout is on page AV-482 and it has the red(camera on signal) and white as power and ground, the yellow and (i guess black) is the video signal and shielding.

Just remember to wire in a reverse signal according to your HU wiring spec/manual so that your HU can automatically switch the video input to display your backup camera when you shift into reverse.

 

Interested. Mostly in how you will mount that thing. GL dude keep updates coming!

 

I finally had time to try & install this this week. I did all the wiring yesterday. I tried to hook up the camera today & there was no picture. When i put the car in reverse, the input on the HU (Pioneer-P3400AVH) switched to the camera but there was no picture. When i checked the back of the HU, i noticed the wire that said reverse signal was not connected to anything (How would the input switch if this wire was not connected?). I then connected a wire from the green reverse wire under the kick panel to the reverse signal wire from the HU. Still no picture (i get a black screen with lettering that says the image may be reversed).

This is how i connected the camera:
(The A/V cable had two wires inside when i cut the RCA plug off. It contained a white & black wire.)

Red wire from camera --> Green/white reverse wire in trunk
White wire from camera --> Grounded to metal
Black wire from camera --> Black wire from A/V cord
Yellow wire from camera --> White wire from A/V cord

When this did not work i tried switching the black & white wires from the A/V cable, but i still had no picture. After swapping wires between each other i decided to check the tail light wires in the trunk. I noticed that the green/white wire everyone said was the reverse wire in several threads, did not go to the reverse bulb socket. The socket has a red/blue wire and & black wire. I'm guessing the black wire is the ground, as it goes to the the other two bulb sockets. When i saw this i tried changing the wiring for the +/-.

This is how i wired it up the 2nd time:

Red wire from camera --> red/blue wire from reverse bulb socket
White wire from camera --> Black wire from reverse bulb socket
Black wire from camera --> Black wire from A/V cord
Yellow wire from camera --> White wire from A/V cord

I still get no image. Anyone have any clue what i am missing?

*I bought two 6-feet RCA cables- red/white/yellow- 6 in total. I used two yellows then a red then a white (I used the red & white when i ran out of yellows). I'm pretty sure all the cables are the same, just different colors for identification. I just wanted to write this so you guys know exactly what i am using.)

 

Pictures of camera wiring please

 

I could be wrong but you may be over your head on this one. It looks like the camera control box uses some proprietary signals for video. In the factory install it will overlay parking lines and other data over the video data. The fun part is the controller requires vertical and horizontal display information from the HU in order to process this data as well as information from a steering wheel angle sensor. It may not even operate on 12 volts if it's getting all of its signals from that controller. Good luck to you sir.

 

Heres the wiring:

I have it coming through the trunk, up onto the trunk hinge, then onto the inside trunk lid. It is held in place with zip-ties (red).







It then goes through the license plate light hole



This is the RCA cable (white) with the male plug cut off. There are 2 wires, a black & a white. (The camera would not focus on the wires, just the background. Thats why it's a little blurry). I connected the black to the shield wire of the camera & the white wire to the yellow wire on the camera.



I used the green wire with the white stripe to power the camera. I read lots of threads & posts that said this is the reverse + wire.



I then switched & tapped into the actual wires going to the reverse bulb socket. (Blue & White wire for power + & black for ground -.



This is the image i get on the HU screen

 

That's exactly what i was thinking initially after reading through the FSM for the G. When a couple of people said it would work, i said why not try. I wired everything up so if this camera does not work, i can simply plug in one of those eBay cameras with no problems.

 

Ok all you need is the composite aignal from the camera(rca) and power/ground hook the camera upto a tv with the rca and hook power up to it and see if you get a picture the recerse wire on the headunit only flips the input on the screen to the camera when you put the car in reverse(alpine) so make sure you ger power and vid signal the go from there.there is nothing else needed to be hooked up dont over complicate it.and btw most of those cameras are 5v so be careful

 

I am going to put this on hold for a second. I am going to order one of those eBay cameras & hook it up to see if it will work. If it works, then i know the G37 camera needs the control box in order to work. I will keep you guys posted.

I also found a way to hook up an LED light under the hood & have it come on only (automatically) when you open up the hood. I have all the wiring parts. Just waiting for the LED's to come in. That thread should be up by the next two weeks.

 

Yeah the underhood led you can splice the geound into the alarm pin switch infront of the battery

 

Smart man! I was going to use one of those pin switches/brackets from the aftermarket alarm systems so i dont have to splice into one in front of the battery. The pin switch is only like $3 w/ shipping. Was going to put it by the firewall on the passenger side. The one for my alarm is on the driver side. This guy on eBay sells some heavy duty silver ones for $3.95 a pair. They are thicker than the ones for the alarm and the actual pin is alot more sturdy. Your idea is spot on though!
