OEM camera install issues

imom. There are two places where the connectors may be in the cab. The driver A-pillar or next the coin holder to the left of the knee, driver side. Mine is behind the coin holder.

I am also trying to figure out R15, pin 2. My 2013 tacoma is wired so the CV+, CV-, Ground, and CB+ are in the four pin connector (second from the top). My
understanding is that the reverse signal wire is one of the wires on the top connector. This would go to the Pin 2 slot in R15. Cant seem to find the information online. Your question may help me bypass this problem.

Pins 15 and 16 of R17 are tied together or can tie together as the ground pins. Pins 8 is the CV+ (video signal itself) and Pin 7 CV- is the 6V that powers the tailgate camera. I would have just bought the cable from the link above, but I'm already needed to run 2 extra wires for the power tailgate lock I bought.


Look at time 1:50 of the video for pin description

I just need to understand how to tap the reverse trigger to turn on the camera on the receiver.

 

This truck is prewired to the Head Unit. My truck is not. So in my case, the reverse trigger is one of the red wires in my previous comment (top connector). Have you seen this video? May help you out.

I think you missed the first link...it's the cabling so it's same as prewired. It's the 24 pin connector and has the 4 wires harness to the tailgate for $40. As I mentioned I would have bought this if I didn't need to run two extra wires for the tail gate power lock. I get that your model is older and maybe doesn't have the reverse trigger...I like to figure that out too, in case I want to keep the stock receiver and use it to select the front and rear cameras.

 

I sure did miss that link. Now I have to check the wiring behind that bumper.

 

The cameras do have a wide angle and anyone can install it for their own purposes but the 170 degree angle does not show the side of the vehicle. The side view cameras will help me through trails without having to stick my - or my passengers - head out the window every time I am in a tight spot.

Pin 2 of the R15 (reverse signal) is a 12v power. I will try to search for the location that I used for this trigger today; It has been raining and I have been too busy to search. I am sure there are other routes that could be used that would be better then what I have but it is hard to build a system without knowing if anything is going to work at all. You could run 18 gauge but after doing much of the soldering that needs to be done for this, I feel that 18 ga

I understand that the pins can be hooked together but if they were intended to be run together don't you think Toyota would have simplified it and run them together? I, personally, would rather just run it how it is designed to be used.

4 pins going to on Monday. I have 4 more pins that I can give away to someone that would need them. I am going to keep the last 4 for later projects.

 

I think you didn't finish your sentence about the 18 gauge...so please let me know. Also to be clear...What I was getting at...so R15 pin 2 is the reverse trigger for the radio. You also tap into that wire for a button to turn the camera at any time you want. So when the truck is not in reverse... this trigger is not at 12V, just high impedance and not stuck at GND. Your switch is tied to 12V I assume? So if you want, you turn on the switch and you get the camera function for left, right, front, or rear. I just wanted to make sure there wasn't electrical contention that can damage the radio.

Regarding the two ground pins of the 4 wires on R17. If you take a multimeter and measure those two pins impedance...you can see if it's 0 ohms..if so...they are tied together. If not...you are correct and you need to connect them as separate wires. Thanks!

 

Hmm. That must have gotten deleted when I was revising what I said. I was intending to say that You could run 18 gauge but after doing much of the soldering that needs to be done for this, I feel that 18 gauge is larger then any of the wiring that I ran into for the camera system.

I have my switch tied to a separate 12v circuit. When I am in reverse, it sends a 12v signal to trigger the camera. When I am not in reverse, I can use the switch to trigger the cameras. I placed a diode in the circuit to prevent any back-flow.

I followed my reverse trigger wire and it led me to the left side of the fuse panel behind the coin tray (1st pic). I am not sure what the connector is called but it is the 13-pin white one at the top left. It is the 4th pin from the left on the bottom row (green).

 

Thank you for that info...very helpful

 

Here is the link that helped me wire my truck today. The backup camera works flawlessly! See ajp's post

Great mod. This will definitely come in handy.

 

Very cool project. Subbed for when I add a front facing in the distant future

 

I just bought one of these for my rear camera. Somehow the guuy has two of them so I thought I would pass on the info. He included the tailgate harness for the asking price for me:

Hey guys, I could be posting this in the wrong area, and if so, maybe someone could direct me in the right forum... I have an 07 access cab with no pre wired back up cam. I'm installing a 2013 non jbl non entune non nav touch screen. I want to make a back up camera work. I will most likely get a stock camera with 4 wires. I'll run cat 5 with wires right from the tail gate (4 for camera and 1 for a 12 v signal from the reverse light in the tail light). I have ordered the 16 pin connector and pins for r17on the back of HU and run the 4 camera wires to there and the 5th back up wire 12 v signal from reverse light to pin 2 on the 28 pin. Does this make ANY sense to anyone? Trying to figure this out before I just throw it in. I have all the other adapters ready to go, just trying to sort out an easy install if i have to run a wire from the back of truck i might as well tie in to the reverse light in the tail light right there instead of cutting into a harness by the fuse panel (which i know is different than the wired 09 and later trucks). Thanks

 

No, this is a good place to ask. I did the same thing that you are trying to do in your 07, in my 08. You have everything correct about the 4 wires and the reverse being needed. You can run a wire all the way to the back if that is what you want to do but there is a wire in the drive fuse panel that would be shorter to access. I have quoted a previous post, below, that talks about what I did for the reverse signal.

 

Thanks for the reply, did you use a toyota touch screen as well then? I see what wire you are talking about, i will most likely do the same as you rather than running it from tail light. So, if i sum this up can you tell me if i have everything i need to do the camera job:

-Stock handle with camera and wiring (will have to make my own connection with plugs at the tailgate to run the cat5 all the way from there to cab)
-Wire the cat 5 into the appropriate pins on the back of R17 16 pin male connector i bought
-Run a new wire from the wire you showed behind coin tray up to pin 2 on the 28pin connector for the reverse signal (12v).

Two questions:
1) do i need to unplug the #2 pin on the 28 pin connector and leave it out and put the new wire in? or is there just none there to begin with?
2) Do i cut the green reverse signal wire and splice into that wire while it remains plugged in or do I unplug it and leave it unplugged and just plug my new wire into it that goes to the HU

This place is full of knowledge, love it!

 

Does the warning from this eBay auction give any unneeded caution on the reverse light hookup?:

 

I have a 2013 touchscreen (non nav non entune). I actually have 4 oem cameras (front, rear, left and right) which is explained on page 1 of this thread. If you read the first page it shows the parts I used, the cables I used and the testing that I did to get mine to work.
There was no wire in position 2 of the 28 pin connector in my truck. I believe it would be the same for you.
You will want to tap into not replace the green wire.

I'd be willing to bet that they are just trying to sell their product. I Agree that it needs power when switched into reverse but there are many people that have used the reverse light as the signal.
During my testing I found that if you put the truck in reverse and then attach the camera, it will not work but if you have it plugged in and then put it into reverse it will work fine.
Another way to look at it is that, if I have camera 1, 2, and 3 plugged in but I'm in switch position 4 none of the cameras will work. If I'm in position 1, 2, or 3 when I go into reverse they will work but if I switch to position 4 the screen will just be black.

 

Isn't the camera power supplied by the 6 volts out of the R17 plug?? 12v is just a signal for the radio to turn on the screen for that function? I am most likely wrong, but thought that was how it worked.
