How to Connect a Relay for Car Reverse Camera Installation

When you are installing an aftermarket head unit upgrade with a car reverse camera, the rear view image on the display may be no signal, flickering, or a similar issue. This is most probably the voltage from your car reverse light is not stable, so it can not provide stable 12V voltage to the camera. Because the car rear view camera should be powered with 12V car reverse light. So that the camera can get 12V power from your reverse light.

If your car can not provide stable 12V voltage from reverse light to the camera, then the camera display will be no signal, or flickering. This is a common issue especially for some old cars. If you have a multi-meter, you can also measure the voltage from your car reverse light.

Solution is to connect a relay between the power source and the camera.

At first, you should know what a relay is, how does it look like, here’s a picture for your reference:

Tips for connecting a car rear view camera

Installing a car back up camera with an aftermarket head unit is not difficult for a professional mechanic. From the head unit side, you should connect 2 cables.

One is the video cable with RCA connector, but please pay attention to the label on the cable, because the RCA cables should come with other plugs which are also with RCA connector, the label may be written as “BACK VIDEO”, or “REVERSE CAMERA VIDEO”, if you have a doubt, do not hesitate to contact the supplier of your unit to confirm which is the video cable for the camera.

The other cable is a loose trigger wire, which triggers the camera to work after you put in reverse gear. It may be labelled with “REVERSE 倒车检测” or “BACK”. If your display can not automatically switch to backup images, you should check this loose trigger wire and see if you connect it correctly.

As we all know, the universal reversing cameras are developed for all vehicles, for those universal ones, you may need to drill a hole from the rear position near the license plate, or you will need to drill 2 holes for screws fixing the camera.

How to install the back up camera for Suzuki SX4

Recently we have a customer who installed a back up camera for Suzuki SX4, we appreciate our customers sharing his experiences when installed the camera and would like to share his experience with anyone who don’t know how to install it.  He has installed a suzuki sx4 dvd/gps unit and a back up camera for suzuki sx4 hatchback.

Below are his detailed instructions.

This is a ‘must have’ when buying the DVD/GPS unit. The connections are straight forward, but the install does take some time. First connect one end of the 15’ cable with an RCA plug (and RED wire) at both ends, to the RCA jack (CAMERA-AV-IN) on the unit. The RED wire connects to the BACK wire on the rear of the unit.

Next, lower the steering wheel and unsnap the cover on the left side of the steering wheel. Then fish the rest of the cable over to the left side cover. Then under the door sill cover, behind the floor seat-belt anchor, the rear door sill cover, up under the rubber molding on the back fender well. Then unhook the upper part of the cover over the little window behind the rear door. Fish the cable over to the rear hatch. Remove the cover on the inside of the hatch so wires and cables are visible. Rather than trying the impossible task of fishing the cable through the boot connecting the hatch to the car, I notched both ends of where the boot attaches. Then fish the cable up the left side of the hatch to where it will be available to plug into the rear camera. Next I took off the left tail light unit. Connect a 6’ wire to the red and black wires of the backup light. The other end will be fished up behind the little window to the backup camera. The black end of the wire will be connected to the black wire on the backup camera. The red end of the wire will be connected to the red wire on the end of the RCA plug AND the red wire from the backup camera.

To install the camera, remove the 4 nuts from the long cover over the license plate. Then unplug the license plate light.
NOTE: put some sort of tool in the loop where the hatch latches when closed…otherwise, you won’t be able to open the hatch with that light wire unplugged. Then remove the left light. (I did not reinstall the left license light.)
You’ll have to Dremel-alter the camera to fit in the license plate cover. This will take some time and patience. When it finally fits, reconnect the cover with the 4 nuts, replace the left tail light, and any covers that were loosened.

NOTE: All wires should be soldered and taped. Be careful when removing or replacing any covers or panels.
Once you have the backup camera functioning, you’ll wonder how you ever got by without it!

Though that’s a detailed installation instruction for the Suzuki SX4 back up camera, please install it carefully, if you are still not good at the installation, we suggest you asking a professional mechanic to do that for you.

Below is a picture showing you how to connect our BMW camera, including all wires connection, the wires connection are more or less the same as the Suzuki SX4 back up camera.

How to install a back up camera?

Have got a back up camera but don’t know how to install it? Don’t worry, with this post there are step-by-step instructions to install a reverse camera. Though installation is very easy for a professional mechanic, it do require some professional knowledge for installation, so if you still don’t know how to install the camera, we highly suggest you find a shop to install it for you.

If you need to connect the back up camera with a car dvd/gps unit, firstly you need to check the wiring diagram for the unit, the wiring diagram can be seen at the bottom of the unit if you got our dvd gps units. There’s a wire labelled with BACK, this wire is used to control reverse control, it should be connected with 12v reverse light power, if you did not connect this wire, the camera display can not switch automatically after you put in reverse gear. There’s also a cable to connect the backup camera from our RCA cables.

This wire labelled with BACK need to be connected with 12V+ reverse light power.

And this is the video cable to connect the camera, usually label with “BACK-VIDEO-IN” or “CAMERA-IN”.

The installation guide for the rearview camera is as follows:

How to Install :

  1. Take out your stock license plate light at the back of your car.(don’t worry, nearly all cameras have night vision)
  2. Fix the camera to where the stock license plate light was.(some back up cameras need to drill a hole to fix it)
  3. Connect the built-in license plate light of the camera to where the stock license plate light was connected to get the power
  4. Connect the power of the camera to your reverse lights – red wire to positive and black wire to negative.
  5. Connect the video cable of the camera to the extension cord.
  6. Connect the extension cord to your car dvd gps monitor.
  7. You will see the images when your car is in reverse shift.

Wiring diagram for installation of the camera

After installation of the rear camera, if you found the rear view images displayed on the car DVD monitor was opposite, then you can check settings > Camera Mirror, change to Normal or L&R Mirror.

Common camera installation issue and how to solve

After installation of the backup camera, if your screen display no signal, or flickering, your backup video is not stable, that’s because your reverse light can not provide stable 12V voltage to the camera, you can add a relay to provide stable 12V power to the camera to fix this issue.
