reverse camera setup

Hi Guys,

I need to figure out which diodes I need (if any) to wire up a after market reverse camera to my Mitsubishi Lancer 05. The camera has a video output, and the power connector has two wires (red,black). My DVD players has a (orange+12v) backup car signal wire and the input for the reverse camera. Here is what I intend to do... wire the power connector for the camera to the reverse light at the back of the car which will provide power to the camera and run the orange cable to the reverse switch at the console where the gear stick is. With a setup like that, my camera will only receive power when the reverse lights come on and will initiate video at the same time when the orange wire receives the trigger. Does this make any sense or sounds like a mad man at work? nonethelss I would like to know if diodes are required.

PS. I have a Eonon 1202 DVD player.

Spot on, no diodes required, if it's any easier join the camera's red wire to the orange at the gear lever reverse switch pick-up. I did that on my Galant, it was more convenient because I went through the centre console, thus one join instead of two.

Hi-

Just wondering if you could help me out with my Backup Camera;

I Have A 2000 BMW E46

I have a Pioneer AVH-P5900 DVD...

I have the PURPLE / White Wire from the Head Unit Connect4ed to the Reverse Light.

I also have the Video Input from the Camera connected to the Head Unit...

I have the Red 12v Wire from the Camera connected to the Head Units PURPLE / White Wire for the Reverse Light for power, when in Reverse.

I have the Ground Wire from the Camera connected to the Black Ground Wire from the Head Unit.

That Said:

When I First Turn On The Head Unit, I automatically See The Reverse Image From The Camera, (Ok, Fine!)

I have to hold the Display button down to switch back to the Head Unit Controls (As Stated In The User Manual), Ok Fine!

But when I am listening to any Source (Radio, DVD, MP3, CD), and I put the Car in Reverse, The Rear Image Does Not Show!!!!

Why??? And How Can I Fix This???

Thanks In Advance!

Hi Vadar1, I did some searching on your behalf and would like to know if the puple/white (+)  wire from the head unit was connected to the reverse signal  blue / YELLOW (+) wire of the BMW E46? Also, the camera video output rca jack is connected to the correct input of the Pioneer DVD player for reverse camera.

ps. according to the manual video switching is automatic once connected correctly, so when reverse is engaged the signal will be triggered on your PURPLE / white wire and change the display to the rear camera.

Hi-

Thank you very much for your help...

Yes! The PURPLE / white (+) wire from the head unit is connected to the reverse signal blue / YELLOW (+) wire of the BMW E46!

YES ALSO! The camera video output rca jack is properly connected to the correct input of the Pioneer DVD player for reverse camera (BROWN RCA JACK WITH LABEL STATING REAR VIEW CAMERA!

Here Are Some Pics Of What My System Shows!

Ok Vader1. Initially you stated "I have the Red 12v Wire from the Camera connected to the Head Units PURPLE / White Wire for the Reverse Light for power, when in Reverse." So that was incorrect, but you have it right now if you did connect it following the information provided above. Now the other step is to ensure the camera polarity setting is set to (+) from the Touch Camera Polarity option on the DVD Palyer - Pg. 47 on manual (this is what will cause the trigger). So pretty much when the dvd player receives the trigger it will switch automatically. If that does not help, you may probably require some additional help from a professional nearby.

Ps. Vadar - If you look at the first picture you posted, it has the camera polrity set to ground - this is incorrect since the trigger wire is (+), so you need to change it to battery.

I have a question also. I have my camera hooked to my reverse lights and all works well. I want to install a switch in the cab that will give the camera power when not in reverse. Do I just run 12v to a switch in the cab then run the wire back to the positive of the camera and put a diode in-between the reverse light and the power with the band facing the light or will I need to install a relay? Thanks

To Jaxon, 12V+ to switch.
Switch output to 86 and 87
Ground to 85
Cut wire from rev lights to camera at relay location. Rev lights to 87a
Camera to 30.

Thus reversing lights won't come on.
You can possibly achieve the same result with two diodes, 1N5404 (3amp). in a Y pattern, in from the switch and reversing lights, bands towards the camera but I think a relay is safer long term.

Now when I wire this up my reverse lights and camera will still come on like usual correct?

Yes.

Awesome thanks.

Ok that didn't work but i failed to give you all the info so my fault. I also need to supply 12volts to the wire that runs to the radio. This wire is attached to my reverse light and sends 12 volts letting the radio know the vehicle is in reverse. So I need to get 12vokts from the switch to this wire and the camera without the truck being in reverse or the reverse lights on. Thanks.

Obvious I would have thought, camera 12V= (i.e. rev light feed) to head unit switched input.

Ok maybe we are both misunderstanding each other. I'm sorry lol. I need 12volts to goto the camera and the purple wire from the headunit when the switch is on and not in reverse. I also need 12 volts to goto the camera and purple wire while the reverse lights are on and the switch is off.

You really are confusing the both of us now.
You need a 12 volt trigger to turn the head unit input to the camera setting, fine the point where the switch output 12volt joins the camera, bring that back to the head unit. This is really too simple to carry on like this.

Sorry doesn't seem simple to me. I'm still not understanding but it's ok thanks for all your help.

Connect the head unit feed to position 30 on the relay I mentioned!

Ok where does the power for the camera go?

This is too basic to carry on but...2 wires + the signal lead on the camera yes?
Black to ground and red? to 30 on the relay.

Ok I have a + wire from the switch to send 12 volts to the camera and the purple wire to the headunit. The purple wire and camera wire also see 12 volts when I put it in reverse. While I am in park or drive I want to be able to turn on the switch and get the same effect as if I had it in reverse. I ran the 12v from the switch to 86 and 87 and then the ground to 85. I ran the camera positive to 30 and the reverse light to 87a but that left no where for the purple wire to go on the relay. Thats the problem I am running into.

Join purple to 30. Yet again.

Ok I'll give that a try

Worked great. Sorry for the misunderstanding. Thanks again!
