backup camera install

celiboom

Hi, I' trying to connect a backup camera to my aftermarket headunit. I've read the whole internet and I'm more lost that ever.

There is a lot of different wiring diagrams. Here is what I have, note that I do not have the wiring that usually comes with.




This is the diagram that I think I will need to use :


problem Is that I can't find that yellow rca with the red wire coming out of it. How can I wire it to my "backup wire" from the head unit?

Here is a picture of what I think I need to do. Please help me wire that "purple" backup wire that will trigger the camera when I put it in reverse. So 2 questions. Is this setup working and if yes, where do I connect the purple wire.



Thank you

Orange wire in the driver kick panel. Grab a multi-meter and test for 12 volts when put in reverse.

I was going to post but I'll let you figure it out, here's a tip...

Reverse wire is accessed behind the tail lights (I used the driver side) you'll see a ton of wires grounded there. Tap that wire for the reverse light.

Headunit has a purple wire reverse trigger, hook that up on the other side.

Not that hard you have 2 wires other than rca

Cut that red wire off the yellow plug. I've ran my own wire so omit electrical noise in the signal instead of using that red one

Highlighting his question here. Find the orange wire in the kick panel that I posted above and wire your backup wire to that.

Some cameras will come with a cable that has that red wire, some don't. You can run a separate wire from the taillight up to the head unit, or you can tap into the orange wire in the kick panel, both described above. Same same really since you need to fish the RCA cable through anyways. But you can save the step of removing the taillight if you just tap the orange.

ok thanks but if I tap in the orange, the camara will be always on? For now, I've removed the reverse light bulb. Only 2 wires, should be easy to tap into it by skinning the wire a little

Orange would only cause the camera to come on when in reverse

Guys im stuck i installed the moonet camera to a pioneer p1400.

Wired the camera to the reverse light bulb. Green to red positive and black on black. is that right?

wired the yellow rca from camera to the head unit. the rca cables both have a red wire on both ends. what do i do with those?

Nothing comes on the screen just black when in reverse.

Regarding the red wire on the rca cable. One end goes to the positive of the backup light (same as the camera power). The other end of the red wire goes to the "backup" wire on the head unit, if it has one. When 12volts is present on the red wire, the head unit knows to display the camera.

The positive wire on the camera must go to the positive of the backup light. The color of the backup light wire may depend on where on the harness you are splicing. I spliced where the harness passes through black rubber grommet to the inside of the trunk. The backup wire is orange or tan color at that location. And the negative is black.

i used the green wire that is connected to the actual reverse bulb. connected that to the red on the camera power wire and the black to black on the same reverse bulb. and i still have a red wire on the yellow rca cable

so you are saying basically to wire both reds (one from yellow rca and the other red camera power) to the same place, in my case the green wire(reverse bulb)?

EDIT: my head unit has a purple wire that says reverse signal, i wired that to the red wire on that side of the yellow rca cable.

SteveK

Yes, both reds go to the backup light power. One powers the camera when the car is is in reverse and the other tells the head unit to display the camera.

hey so i double checked all the wiring, and the ground.it is all in place and i should have it correctly? camera still does not display anything on my pioneer avh p1400

i used two different rear view cameras to plug in and they both dont display anything

can you verify if i am able to use power from the reverse light bulb wire
it is a green wire im assuming for power and black for ground?

bigaudiofanat

That purple wire you're questioning from your head unit MUST be ran to the trunk to an orange wire on the left hand side to tell the head unit you're in reverse.

The camera turns on when I hit reverse it just doesn't display anything that's the problem.

The rca cables have a small red wire that you can use for the reverse signal. I think my problem is that the camera it self is either grounded bad or not getting power. I'm using a separate ground and using the green wire that is connected to the reverse light bulb. Should I be using the orange wire for power for the camera ????
