How can I add a second backup camera on my removable swingout on a 2020

Are all the slots populated (wired) on your Taco's connector?

 

No, only 5 slots populated.

1 black
2 white
3 red
5 green
6 blue

 

See post #10 again.

 

Got it working! Only 5 slots populated on the 8 pin connector.

1- CB + VIN
2- CV + (camera yellow/center pin)
3- CV - (camera red/shield)
5- CGND

 

I have a 2017 TRDOR. Since I recently bought a RiG’d swing arm, I need to relocate the backup camera. Like most of you, I made a backup camera harness that will plug into my existing (4 pin) tailgate connector. I have already installed a front and side camera, so I am familiar with the installation of cameras, but for some reason, I cannot get the Natika camera to display on the screen. I am hoping that someone here can see what I am doing wrong. I’ve extensively searched TW and the web and have found a lot of confusing or conflicting information. Here’s a summary of what I found.

Thanks to @caribe makaira, I have a pinout diagram for the 4 pin connector. Notice that in the below diagram, pin #1 (White) is CV- and pin #2 (Red) is CV+. The importance of this will be seen later. Can anyone verify if this is accurate for the 2017 OR?


Below are all of the wire labels I used to make my pin connections. The photo to the right is the one provided by @shaggy135 in post #70 which shows a working camera harness. The pinout for this harness is the last set to the left. As you can see, pin #1 is CV+ and pin #2 is C-, which is contrary to the above diagram.


WIRING THE HARNESS

I measured 6 volts in pin #4, so I attached the Red wire (CB+) from the zipcord. Pin #3 received the Black wire (Cgnd) from the zipcord. Due to the conflicting CV+/CV-information, I first wired pin 1 to the RCA connector Yellow (shielded) wire (CV-) and then connected pin 2 to RCA Red wire (CV+).


I put the truck in accessory mode, pushed the anytime backup camera button and observed the obstructive camera view on the screen. Next I disconnected the camera connector under the bumper and attached my harness. No image appeared on the screen, so I reversed the wires in pin locations 1 and 2 which changed the connections to CV+ and CV-, respectively.


NOTE: This is the same wiring configuration as in post #70 (see above for the m nguyen pdx wiring pinout) Unfortunately, I get the same blank screen using this pin configuration, too.

I was able to find a defective camera that I replaced a few years ago. I think the only issue with it was that it flickered when it warmed up. I’ll swap out the Natika with this one and if I can get an image on the screen, I’ll know if the Natika is defective. No image will be less definitive.

Any other ideas? Is there a “reset” button on the Natika cameras? Thanks for any help you guys can give me.

 

I have the same truck model and year as yours and a Rig’d swingout as well. I also used the same camera. This is the connector I used and it all worked based on #70.

I bought a similar connector pigtail. Other than the variances in the color of the pin wires, they all seem the same. BTW, you scored on the swing arm you bought. I live in SD, so I would have bought it if it was available when I was looking for one. I found mine in Texas and was fortunate that my brother was driving home from an east coast vacation and was passing through where the guy lives!

 

Although I gave nothing to add to this thread, I wanted to stop in and say @caribe makaira you're a badass. You have shared so much knowledge on this forum. You should be MVP status. Wanted to say thank you for all you do.

 

The OEM camera uses 6v DC, I don't know the voltage range of the Natika, but I know it's not 6v. So you'll need to provide a separate fused power source for the Natika and only mate the video pins to the OEM harness. Towing T12 connector has a 12v source that can be tapped into.

 

I think it's just your wiring. There are a few variations of this plug. I'm my post #60 of this thread, I put my wiring combos.

Pin 1 - Camera + (1) Top left on the camera side of the plug goes to the red wire in the housing
Pin 2 - Camera - (2) top right goes to the other wire inside the housing
Pin 3 - Voltage - (3) bottom left is the ground
Pin 4 - Voltage + (4) my bottom right wire is power

 

Per Natika support, the camera requires 3.5-5V and this voltage is achieved by using their standard 26ft extension wire. I imagine it must have a voltage converter in the wire splitter junction "box".

I finally got my camera to work! Thanks to everyone who offered their help. Shaggy, you were partially right, it was my wiring, but using your wiring configuration did not work for me. Pin 3 and 4 were the same, but the video wiring is different.

I removed the yellow insulation jacket on the RCA connector in order to see that the CV+ is actually the YELLOW wire and the CV- is the SILVER GROUNDING wires that surrounds the yellow wire. The Red wire is the optional trigger/power wire. As a result, I made my connections based on Caribe's 4-pin diagram:


**************************************
OEM PINOUT: (WIRE SOURCE)
(1) White = CV-; (2) Red = CV+ (RCA Connector)
(3) Blue = Cgnd; (4) Black = CB+ (Red/Black Zipcord)

EBAY GRAY CONNECTOR - CAMERA SIDE:
(1) GRAY; (2) BLUE
(3) YELLOW; (4) BLACK

NATIKA CAMERA WIRES:
Red = Power/Trigger (+); Yellow = CV+; Silver wires (non-insulated) around Yellow = CV- (RCA)
Black = Cgnd; Red = CB+ (Zipcord)

EBAY-TO-NATIKA PIN CONFIGURATION:
(1) GRAY = Silver non-insulated wires (CV-); (2) BLUE = Yellow (CV+) (RCA)
(3) YELLOW = BLACK (Cgnd); (4) BLACK = RED (CB+) (Zipcord)

**************************************



Since my configuration is working using the loose ground wires for CV-, I'm baffled how others were able to get their cameras to work using the Red trigger wire in pin 1 (CV-), like the lower right picture.

In any case, here's another wiring option for anybody who is still have problems getting their camera to work.

 

I really appreciate you guys sharing your time into this. I'm several hours in and finally sorted it out, so hopefully the following photos are helpful.

I powered the camera with a benchtop power supply so that I could trust the 12v.
I was only seeing 6V from the white wires and I wonder if the JBL unit can deal with this better. Mine flickered on and off every other second or so.

I had the video feed wired correctly, but the power seems to be right on the cusp of working for some and not others.

I didn't need the blue wires, or the one red and black on the truck side, or the red wire on the camera side.

These photos are the 6v wiring option, but I will finalize mine by pulling power from trailer circuit.

 

This is what worked for me as well

 

Hey, Happy Sunday!

sorry for reviving this oldish thread.

I am installing an aftermarket rear backup camera and am following this diagram.

I have a few questions because I just cannot figure out how this Video Cable is supposed to be spliced to the

$11 Compatible with Front Radar/Sonar Sensor Connector 8 Way Pigtail for Toyota 90980-12520

8 way pigtail harness.


Here is the cut VC with the red trigger wire.
The VC had the red wire and yellow wire with the shield wire grapevined around the yellow.

Are the yellow and shield wire supposed to connect to pin 2 and the red wire connects to pin 3?

I have tried..
1- CB + VIN
2- CV + RED
3- CV - YELLOW/shield
5- CGND

and am getting no screen feedback.


I was hoping this could get clarified, thank you if you can answer any of these questions.

 

Caribe's diagram shows the OEM colors (I believe). If you are using that exact pigtail off scamazon:

6 is black on the pigtail and black on the diagram and should be mated to the red on your video cable which carries power to the camera.
2 is also black on the pigtail (note it's a different wire though) which is super not helpful and is red in the diagram, it should connect to the bare wire shield which wraps around the video wire.
3 is red on the pigtail (also extra confusing) and white on the diagram, this should connect to the yellow video signal positive input
5 is white on the pigtail and should be sent to chassis ground (look for an OEM ground if one is within range)

CB+ == camera battery power input, typically 12v for aftermarket cameras but I defer to the rest of you on specific cameras
CV- == camera video negative aka camera video ground aka camera video shield, bare wire wrapping around the camera video positive signal shielding it from EMI interference
CV+ == camera video positive, this is the actual signal (relative to shield ground) containing video from the camera to the display
CGND == chassis ground, this is the reference for CB+ to supply power to the camera, DC power needs + and ground.

Hope that helps a little bit? If you're not using the pigtail from scamazon then the wire colors I mention for the pigtail do not apply to you.

 

Thanks for the that! I got the CV - and CV + settled now I am still got getting any video feed.

Currently setup with...

Red / connected to
Pin 6 CB +

Black / ground connected to
pin 5 CGND

Yellow / shield connected to pin
2 CV -

Red / center connected to
pin 3 CV +

pin 1 unused

I have tried the red wire for both Pin 6 and Pin 1 to see if it's one or the other.
Here are photos of my wiring job.



I have flipped flopped connecting the black wire from Pin 1 and Pin 6 and am still getting no results.

 

In a photo above I see red, yellow and bare wire. I assume those are cb+, cv+ and cv- respectively.

 

Yes, yellow shield is connected to pin 2 on the harness cv -
Red is connected to pin 3 / cv +
Black wire is pin 6 CB + on the harness and is connected to the red wire that is jointed with the black wire that goes to the Pin 5 CGND.
Thanks!
