Help Please With My 2013

Was having no backup camera issues with my original factory set up. So I decided to get a new head unit and a new 12 volt camera.

Installed these and I have no backup camera. So I grabbed my video feed and my 12 volt reverse trigger from the wires down by the fuse box. However I needed 12 volts for the new camera. So up at the mirror I cut the red 12 volt reverse trigger wire ( confirmed was receiving 12 volts when in reverse ) and I also cut the black wire ( previous 6 volt positive ) and soldered those two together.

According to my calculations that should supply my tailgate camera with 12 volts. However I am not getting any voltage to the camera. Prior to starting this I was getting 6 volts to the camera so the black wire should be good.

Just checked the soldered connection i made up by the mirror and am getting 12 volts at that connection when in reverse. Why am I not getting any voltage to the camera?

 

I have no real idea on electric stuff but if you put the two together wouldn’t the 6v now be getting 12v and not be happy. I’d look for a blown fuse but start by unfucking the wires.
Good luck, I’m sure someone will have a better answer.

 

When you initially had a no backup camera issue, how did you determine it was a bad camera and not a wiring issue?

 

Well I only partially confirmed it was not a wiring issue. I had 6.78 volts on the black wire at the end of the harness. Was unable to find a new 6 volt camera but so I decided to get a new 12 volt camera and a new head unit and swap them. I did ohm out the 4 ft harness from the camera to the connector near the frame and all 4 legs had continuity. But didn't have a wiring diagram so didn't know where the other junctions were in the system.
Now I have no voltage at the black wire on the camera end of the harness. I am having difficulty getting continuity on any of the segments of the harness. Looking for wiring information/diagrams for this circuit.
Guess I could have just blown a fuse during the install. I'll try to find out which fuse involves the backup circuit. It's not the fuse for the reverse trigger as the reverse trigger has 12 volts.

 

You checked all the fuses...

This is your 6th thread on camera issues. It would help you, and the people trying to answer your questions, if you kept it in one thread

 

I received little to no response in my other threads. Then as I went I incurred other related issues. Had I received any input I would have stayed within one thread. Been battling this issue for several months.
Going to check all the fuses however upon a little research there is not a dedicated fuse for the backup camera.
Also wondering if it could be one of the connections with the new head unit. The Ainavito instructions are very poor. All the other functions on the head unit seem to work correctly.

Thank you for the diagrams.My wiring is slightly altered now due to the head unit install.
I am thinking the issue I'm having is related to the head unit install. I attempted to get continuity from the connector to the mirror and the red, white and black wires from the connector at the mirror to the connector at the camera. Was unable to get continuity on any of those three wires so they are interrupted so where in the system where before the head unit and 12 volt camera install at least the black wire had continuity.

 

I removed the 6 volt camera and installed a 12 volt camera.i then supplied a 12volt source to the camera by hooking the 12 volt reverse activation wire to the former 6 volt positive camera feed wire. So now the camera is receiving 12 volts or it would if system was functioning. The black ( former 6 volt positive) is just a wire so it just allows whatever voltage is supplied to it. Don't know where the voltage was formerly switched from 12 volts to 6 volts but it is no longer supplied with 6 volts as it has a 12 volt supply now.

There is no dedicated fuse for the backup camera. So as everything else is working it can't be a fuse.

 

6.78 volts is a very, very odd measurement. Taking a wild guess I would say you have a high resistance connection somewhere in the harness.

Find that issue and you should be able to un-hack everything and put it back to factory.

 

Backtracking on my previous post. Im not familiar with the factory camera setup, but did find some info in the manual that it may in fact be 6v

Still not sure I follow why you jumped 12v to 6v though

 

My opinion is run clean wiring to your camera and don’t tap the OEM cam system lines.

Im assuming your headunit has a video-in for a backup cam and all that. Usually these cameras you just need a video cable to the headunit and then tap the reverse tail light as the trigger. They usually just have a video cable with a pre-run trigger line with a short length of exposed wire on either end to make it easy. But it sounds like you cut all the wiring up.

You are trying to get the camera to display in the rear view mirror?

Edit: just my assumption here perusing the wiring diagrams but it appears to me that by you cutting your reverse trigger at the mirror, you have cut the signal for the display to turn on when in reverse. Sure you are sending 12v to your camera, but you don’t have a trigger for your mirror video screen to cut on anymore.

 

I believe OP cut this wire so it no long supplies 6v to the rear camera. Once he cut it, he spliced the end that goes to the rear camera to the 12v reverse wire. This would supply the necessary 12v to his new camera.

 

Guys,
I didn't hack my wiring, ruin my wiring or f up my wiring. I made modifications to the factory wiring as to no longer display the camera in the mirror but in the new head unit. My 2013 head unit had no provision to display the camera.
I am fairly confident that most that responded to this thread have never done this mod, due to the comments in this thread. I an fairly competent at automotive wiring and wiring in general. Also I followed a very good you tube video from a very competent mechanic which is listed below.
Not going to rewire my truck. There is obviously something not connected correctly. This exact mod has been done numerous times to 2nd generation Tacomas. Probably just with head units that come with better directions which this Ainavito unit has very poor directions.

That is indeed a very wild guess. The 09-13 Tacoma back up camera system operates the camera on 6 volts. To install an aftermarket head unit the system must be converted to 12 volts or if maintaining the original 6 volt camera a "Pac 39" device must be wired into the system to revert the
Camera feed back to 6 volts.
So to put everything back to factory wiring mods must be done which I elected not to do. Converting the feed to 12 volts is much less wiring modification and makes much more sense.

 

Your description of your wiring, the fact you are trying to splice in an aftermarket camera to your OEM camera wiring and run it on an aftermarket head unit is the most roundabout way of wiring an aftermarket 12v camera to an aftermarket headunit. If I’m way off base from reading what you posted originally then provide a drawn schematic of what you did. The fact it isn’t working is contrary to your post I’ve quoted.

The most straightforward way to wire a aftermarket camera to your unit is plugging in the video cable directly from the camera to the aftermarket unit and then grabbing a trigger/reverse trigger. It’s that simple on any aftermarket install.

2013’s fwiw can display the camera feed on the headunit. There used to be vendors selling a harness to do so easily but the aftermarket support is obviously gone for a 10+ yr old truck.

I followed the you tube video in post #16 as far as wiring with the exception of using the reverse trigger wire to provide 12 volts to the 12 volt camera which was no longer needed at the mirror as I no longer desired the camera to be displayed in the mirror.
In addition I suspect my original 6 volt camera to be faulty. I looked high and low for a 6 volt camera. Probably the only place to buy one in from Toyota. Not only that the new head unit has wifi, Apple car play and my maps can now be displayed on my head unit. None of that was possible with the original unit.
I'll get the camera working eventually. I just figured someone else here had used this same equipment. Actually some have but they have failed to respond to my inquiry.

 

Ok, let me just ask a clarifying question so I am on the same page as what you have done.

Are you splicing your new 12v camera into the pre-existing wiring at the tailgate?

If the answer is yes, then I follow what you are doing. If the answer is no, then I will ask follow up questions.
