Hi Everyone. Just to complete my explanation of how I retrofitted a reversing camera to my Abarth 124. I was stripping the dash down to install the hardware required for the Carplay mod (see elsewhere in this forum for details). Installing a reversing camera at the same time is a relatively simple job.
You need the following parts:
This cable: https://www.aliexpress.com/item/SINO...736834411.html
currently $12.88 inc shipping worldwide
This camera: https://www.aliexpress.com/item/Rear...862866456.html
$10.88 inc shipping
This DC-DC converter: https://www.aliexpress.com/item/2018...890747900.html
$1.75 inc shipping
This gives us a total cost of < $25.
The cable comes with connectors for the video feed from the camera mounted in the bootlid, as well as a connector that provides 6v to the camera. Somehow the cable is wired to notify the display to switch to the video feed when the car is put into reverse. So we dont need to worry about 'enabling' the reversing camera, the cable takes care of this.
We need the DC-DC converter because the camera requires 12v whereas the car feed supplies 6v.
The car comes with a hole in the bootlid where the camera fits. This hole is normally filled with a blanking plate that we can pop out. The camera shown fits perfectly in the hole. When popping out the blanking plate there is a sponge washer that we need to re-use when fitting the camera into the hole. This ensures a weatherproof seal.
We need to run cables for both the video signal and the power feed from the back of the audio unit to the bootlid where we will mount the camera. The camera comes with the necessary cable for both feeds.
Please see the attached pictures for details of how to install the camera and cable. Please note from the picture that while the field of view provided by the camera is not perfect, it is good enough!
As shown in the pictures, the DC-DC converter can be spliced into the power feed at the back of the camera.
I used a coat hanger to feed the cables into the rubber boot that carries the cables into the bootlid.
Please feel free to ask any questions about anything that is unclear.
