Help Please With My 2013

No I simply plugged the new camera into the factory harness at the tailgate.
The only two wires I cut were the 12 volt trigger wire and the positive voltage wire. I cut those at the connector at the rear view mirror. Perfectly legit way to get voltage to the camera and as I stated the reverse trigger wire was no longer needed there anyway.
The other wires which are down by the fuse box I only removed the casing and then soldered new wires to the existing wires. Those wires were another reverse trigger wire for the head unit and the positive and negative video feeds again for the head unit.
That is the extent of the wiring mods I did. Everything else is plug in connectors at the head unit.

 

Ok that was what I figured. I completely follow you on sending 12v down the OEM line to the aftermarket camera.

Is this a Tacoma specific aftermarket 12v camera that has the same connector as OEM? It came with your aftermarket headunit?

 

Yes it is a Tacoma specific camera but it did not come with the head unit. It's a Green Yi camera that I got on Amazon. The head unit is a Ainavito that I also got on Amazon.
The head unit also had a camera with it but was very generic and although I didn't really investigate it's installation i think it gets powered by splicing into the wiring for the reverse lights.

 

Do your reverse light come on when in reverse?

 

Yes they work as normal.
I am fairly confident that while my backup camera was not working the camera not working still is related to the installation of the head unit.

 

Auto or manual trans?

 

Manual
The existing wiring and switches are good. Prior to this installation voltage was generated on the black wire for the positive camera feed when trans was shifter into reverse. I confirmed this with my multimeter. That's how I knew the signal was 6.78 volts.

 

I found your Amazon link to the camera in your other thread. I didn’t see anything about it being 12v. Would be weird to be an OEM replacement and be a 12v cam.

edit: nvm I see a reviewer says it’s 12v. Just a shitty product listing.

 

My opinion at this point is given your OE camera crapped out, I think there is a wiring issue or damage somewhere between your camera and your fuse box/junction connectors. Could be a broken wire, corroded connector, etc. would explain why the original cam malfunctioned and why the aftermarket doesn’t work.

 

So, just to clarify, you're using the existing plug from the oem camera? Are you getting 12v at pin 2 of that harness while in reverse?

 

The factory camera is indeed 6V, meaning a 12V camera won't work with any of the factory camera wiring since there are safeguards built in to the factory camera circuit to prevent overdraw by the rear camera in the case of a short (IE - 6V going up to 12V).

Not sure why Toyota chose 6V for it, my guess is to reduce power demand / heat or maybe to better supply power to the camera from the head unit directly?

From my own experience, you've got two options -

1) Wire your new camera directly to the head unit with whatever wiring came with it, assuming it came with a yellow RCA video plug that will plug directly in to your head unit. Provide power & ground out the new camera with the wiring that came with it as usual without using the any of the factory camera wiring. From there, unf*ck the splice job you did (IE - rewire it back to how it was from the factory) to prevent other electrical issues from popping up down the road.

or

2) Unf*ck the splice job you did (IE - rewire it back to how it was from the factory) and use this harness to retain the OEM functionality of your original reverse camera.

I'd bet $1 your factory camera still works just fine, it's just not receiving the correct voltage from your new head unit, or the rest of the vehicles 12V-ish power system.

Not trying to be harsh, just trying to steer you in the right direction. We've all been there bud haha

 

Yes I am using the original factory harness. Prior to installing my new stuff I was getting voltage at pin #2 when the trans was put in reverse. At present I am not getting voltage there with trans in reverse.
As I already mentioned I am not getting continuity on any of the wires in that harness from where it clips into the mirror to where it clips into the camera which I believe is the entire length of that harness.
That is why I think it is something not connected correctly and again the Ainavito head unit has poor install instructions. Read some reviews about it on Amazon. One won't have to read many before the instructions are mentioned.

 

Check you tube or the reviews for the Ainavito head unit on Amazon.There are several threads and many reviews where people used 12 volt cameras in 09-13 Tacomas.

I have done a lot of research on this. The 12 volt mod is possible.

Also one cannot use the new head unit without wiring mods. That is not possible.

 

Sounds like you know where the problem lies. What about pin 7 from the harness going to the mirror? 12v in reverse?

 

This is going to sound a little harsh but I don't know any other way to express it. There is a lot of bad advice given in this thread. Those that dont understand or know what you are talking about should not be posting.
Currently I am slightly miffed at why I am having issues but I know enough about vehicles and mechanics to know something is untrue when I hear it. Some other poor unsuspecting soul may not be as familiar with things as I am and could follow some of this bad advice which could put them in an even worse spot.
Now this is going to piss some of you off but it wasn't meant to. It is meant to be a reality check.

 

Yes I have it and it works. That is what I used to supply the 12 volt camera feed.

 

So you have 12v at the I8 plug but not at the T19 plug, correct?

 

That harness is not even applicable to my 2013.
As already stated I feel bad for those that don't know any better. Some of you should stick to things you know about.

 

This is pretty funny coming from the guy who screwed up the install in the first place.

What’s funnier is that most people wouldn’t end up having to read this sub online because they just followed the instructions that came with their camera lol. You know, the same way the pros do it.

You did see the instructions that came with your camera, right? Option 1 in case you’re not tracking.

To anyone reading this sub down the line - don’t do what this guy did, just follow the instructions that come with your camera.

Good luck with the fix. Don’t start a fire haha. Plenty of threads on how to do this job the right way.
