Need Wiring Help with reverse camera (2016 CX-5)

[BClark75]

Hi all,
I have a mazda cx5 2016. I purchased a backup camera kit from Amazon, and to no surprise it was missing wiring instructions. Here is a pic of the kit:

I expect the blue wire near the camera should go to a reverse light for reverse signal

,

and assume the red wire from the adapter wiring harness

should go to a revers connection at the radio (but am not sure where).

The blue and black/red connectors from the black box I assume are for power but have no idea where they should be connected.

Can anyone help?

The kit also came with an alternative RCA wire with yellow only RCA and a red wire on each end.

Instructions seem to be shown in your pic. Contact Amazon and request a replacement - hopefully that will have them included.

I might be returning this as a result

Do you have a link to the product?

It might have a better picture than the original, from the specs. Have you looked at the back of your unit to see if the plug even fits? I seem to remember reading here that the OEM cameras are 6v. I don't know if that is a problem or not.
They don't seem to have much help on the amazn site, no reviews or comments.
Are you replacing an existing camera or adding on?
I added a camera (from Amazon) but as I had no flat panel infortainment I had to add the screen as well. I remember reading other posts on this web site about cameras.

I haven’t opened up the dash yet, but I remember the connectors from doing my CarPlay upgrade. They should match, and I’ve compared to what’s online although I can’t find a solid pinout chart. I’m adding the camera not just replacing.

In my opinion, after reading the specs and how the manufacturer seems to play it's usefulness up with all the useless specs, I'd return it. 180 degrees of view makes me wonder exactly where the focus of center is. It may be compatible with your car (and many others) but the installation might be a real issue. I suppose that's why you would have a professional install it. If so, I can imagine your bill: #70.00 for the camera, $200.00 for the installation. I couldn't help but notice a 1 Star review with 0 positive reviews when looking at the buying options. Run, run really fast.

based on some competitors information, I've been able to piece together the following:

It would seem the black box is a 12V power rectifier, but where do the leads attach? The blue one may go to the "Back" signal from a cable at some spot behind the head unit to provide signal that the car has gone in reverse, but I have no idea about the black/red wires. See competitor product below, along with their wiring diagram that also does not show the rectifier or its connections:

Honestly, if the kit is "Plug and Play" it would indicate so. If you can't make sense of the installation wiring without guessing, probably no one can. If you go this route, Tylenol is on sale at Walmart right now.

Not sure what black lapping should mean

OK, the black (lapping?) wire should go to a ground point on your car. The red wire needs to be connected to an "accessory" 12V supply - i.e. one that is powered when the car's ignition is ON. I suggest you find a suitable fuse location and use a fuse tap (AKA "Add-a-fuse") for this.

If you don't understand the above, or it is too much for you, then go to a car audio installer and have them do it.

I think this will work! Let me know if anyone sees something wrong.

Thank you for all of your help!

SUCCESS!!!!!!!

Hi all,

After many trials and tribulations, as well as a refund from the vendor for not being able to support, I was finally able to piece it together with the support of about three separate videos on youtube. It turns out the kit as originally shown and advertised for Mazda cx5 2015-2016 is actually what you need for 2012 to 2014. These models have 12V at the head unit, but the camera is 6V, and therefore the need for the stepdown.

For the 2016 model, you simply need to power the camera from the internal tailgate light (blue wire) and chassis ground in the tail light. This goes to the red RCA connector of the camera. The yellow RCA of the camera goes straight through the vehicle to the adapter cable supplied in the kit. There is no need to connect the blue wires at all, or tap into the reverse light as the head unit does not have a camera reverse signal input, but already has reverse input that is triggered when the camera is properly powered BEFORE the car goes in reverse. This was very simple, but the advertised kit was overly complicated.

If I could do it over again, I would use a simple (long) shielded RCA cable with the adapter. I have also ordered another adapter to more simply tap into the internal tailgate light without having to splice and solder as the 20 gauge wires are so fragile to work with.

Below you can see the kit, and the connections for anyone else looking to do the same. I've provided a simplifed view as well so if you would rather just buy a simple RCA cable - this would be MUCH easier to pull through the rubber tubes between the ceiling of the car and the tailgate as the splitter and double RCA jacke was very difficult (had to tape the jacks in opposite directions and still had use grease to pull the wires through).

Good to get it working . How is the quality of the video?

not the best, and a little off center due to using the licence light port. Since the vendor refunded me for the kit, I've ordered a better camera which I will install more in the center
