Hi, I just added to this thread on post 72 on page 5. My install was on the 2013 which I think changed all the wiring schematics. If you haven't purchased a head unit yet, try calling walt at ADC Mobile. He can set you up with the correct harnesses for your intall and possibly avoid splicing all together.

I pulled this from his site. Hope it helps.
All 2008-2012 non-navi Highlanders have the camera display on the upper Multi-Function Display, and the Advent Highlander navi comes with a “T” harness that allows a plug and play connection to the camera. However, when the vehicle has a factory navi system, the camera is displayed on the navigation system and will take some rewiring to get it to display on the Advent’s screen. The diagram below shows the connections that are required.
CAUTION: The factory camera requires 6 VOLTS to operate. You must obtain or build a 12 volt to 6 volt adapter to allow the factory camera to operate properly! IF YOU RUN 12 VOLTS TO THE FACTORY CAMERA, IT WILL FAIL!

 

This image of mine should be self-explanatory, if you have Q's, just ask :thumbsup:

 

That's awesome, thank you. One thing I'm missing is on the non-nav side, where's the reverse wire?

Also, does anyone have any idea if someone makes a harness for that e11 connector?

 

Sorry, didn't realize that wasn't on there, Rev is Pin 2 red wire.

Make sure you power it with 6V like solisbc said.
V+ is video signal
V- is shielded ground
CA+ is 6V power
CGND is ground

Did you get the bit on the gauge cluster? The grounding the pin to disable the MID from bringing up the rear view?

 

No problem. I did catch the gauge cluster part, thanks for checking!

This helps a lot. Now if I could just find a harness for this connector to help cut down on factory wire splicing

 

Oh, and just to clear one thing up...

I need to supply 6v to the ca+ wire, correct? And I'm guessing I can just send cgnd to the head unit's ground.

Any ground theoretically should be fine, but might as well make it the headunit just to prevent any potential interference sneaking into the video signal.

 

One more question: where should the 6v lead be tied into after being stepped down from 12v? I would imagine accessory 12v+, but just want to make sure.

 

You have me a bit confused, you mean the source for the 6v? The FSM states it should be hot only when in reverse, so you could use the 12v reverse wire. Though some people have just wired it into an ACC source without issues.

 

I would call Walt at Adcmobile.com and get the right harness so you are not having to worry about splicing or making a voltage converter.

 

Sweeneyp that's exactly what I was after. Thanks!

 

So I ran into a problem. The wire harness behind the gauge cluster doesn't actually have a pin in the 18 slot. Got everything else working though.

 

Yeah....not sure how to fix that one, sorry :lol:
