Those wires should be for power and ground. I would connect them all. But if you're using an aftermarket camera you may not need to go through all the hassle I went through, as that was due to needing to connect a stock Sienna backup camera which is 6V. Your Eclipse camera probably requires 12V to begin with, no?
 
Doesn't Eclipse ( Fujitsu ten ) makes OE camera and nav for Toyota ? Cos the factory Nav is totally Eclipse interface
 
Hi, I just wanted to say thank you for the great write-up. I was able to follow this to install my Pioneer AVH-4000NEX in my 2013 Sienna XLE with factory NAV while retaining the factory backup camera.

Monster cable, only the best!

Steering wheel control box

Steering wheel control plug and play and retain factory AUX IN port

12V -> 6V converter

USB retention cable

I used these to tap the video + / video -, backup camera power, and reverse gear sensor in the van so I didn't have to cut and splice any wires.

The only word of warning I will give you is if you have factory NAV like I did you might not be able to use any of the dash kits. My trim piece for the factory stereo was all one piece with the vents molded in!

I actually had to buy a different factory trim piece to make this all work, part # 5540508020B0. It's about $235 from a dealer new, but I managed to find one for $100 used from an auto recycler on eBay.


Overall I'm happy! It was a bit more than I wanted to spend to install but I'm excited to have Carplay back in my road trip vehicle!

Looks great! Glad to hear it worked out for you. Thanks for sharing your install pics too.

I also found out about the different dash trim you need if you have factory navigation when I was trying to put it all back together, and had to pay $200+ to get it from an online dealer since I didn't want to wait at the last step and it didn't seem easy to find. If I could do it over though, I would have used some of those wiring harness adapters so that I didn't have to cut all the original harnesses to make the connections and splices. Guess it doesn't matter too much though.

I've thought about getting a CarPlay HU too but I really don't want to mess around with the HU at all for at least a few more years. :)

Enjoy your new stereo, looks nice!
 
I recently installed a kenwood deck into my 2012 Sienna se. Followed all the instructions and everything works perfectly except that my kenwood deck has a back up camera button that you can press for 3 seconds while in any gear or driving and the rear camera will come up. With my current install I am able to get the camera to come up but it shuts off after some time. I tested to make sure if it happens after going certain speed but could not determine it since it randomly shuts off. Any ideas how to bypass this?

I have a Kenwood too (see my sig for specific model) and I know what feature you're talking about. I am able to use it in my Kenwood (I assigned it to the "tel" button I think and it shows the rearview camera view continuously until I toggle it off) so not sure why yours doesn't stay on. I do use a little bypass device so that I can play DVDs on the monitor while driving (for my kid to watch on the rear monitor) but that isn't involved with the rearview camera at all. What model Kenwood do you have? And it comes on and stays on when you're in reverse?

You could also try calling their customer service. I think I called them due to some issues with DVD playback with my Alpine rearseat monitor and IIRC they were pretty helpful.
 
Hey it's an old kenwood DNX5120. I just grounded the parking wire which bypassed the DVD mode while driving. I didn't have to do anything else for that. But rear camera is pissing me off. These are the instructions thatch i followed. Everything works. Both screens come up while in reverse.
(Black) pin 3 - Reverse signal. This becomes 12V signal when transmission is in reverse. Check it with tester if you have one.
(Black w/ Silver dots?) pin 14 - Video+. Center connection on RCA plug.
(White) pin 15 - Video-. Shield of RCA plug.

So can you tell me where the tel line got connected.
 
I've been going at this for 2 days in my 2014 Avalon. I understand that I need to provide 6v via a 12->6 step which I have for the OE camera. I'm trying to get that camera to work with a new Kenwood hu. I've tested every lead in the factory harness and CAN NOT find a pin that changes voltage when the car is in Reverse. Could the stock radio be receiving the Reverse signal encoded through a BUS or something similar? I cannot understand how the stock unit sensed when the car was in Reverse for the life of me. Any insight?
 
Is correct to assume that those with a LE that have that little screen to use as the backup monitor will not need a step down converter when installing a new head unit ? I figure since the little screen will continue to power the cam and I will be just tapping into the video signal.
 
Bump the above question. I am about to install an aftermarket HU into a 2014 LE with stock backup camera to the little monitor. I expect to tap into the video signal and need to wire the reverse signal to the new HU.

If all that is correct, do I get the reverse signal from the stack monitor? Or do I get it from the reverse light in the bottom left side of the dashboard?

10 months late, but yes I believe you don't need to convert 12V>6V if your stock back up camera feeds that little screen above the dash.

You have to identify which wire in your stock wire harness is the reverse wire and then connect that to the stereo's reverse wire. I did this so long ago that I can't remember how I identified the correct wire but it was probably one of those wiring diagrams from the Toyota tech website (that you have to pay to access). The wiring can change from year to year so to be safe I would check the wiring diagram for your specific model/year/trim.

2. Connect the reverse wire (from the stock wire harness) to the aftermarket HU's reverse detection wire to display the video from the backup camera when in reverse.

Wish I could help but I checked my wiring schematics and they are only for the trims with navigation but not JBL. You should be able to find that from the Toyota tech site which doesn't cost too much for a one day subscription IIRC. I believe you can also use an iDataLink Maestro to connect your factory backup camera if you have your factory wiring harnesses (I will never forgive myself for cutting the original wiring instead of using a harness as I can't use Maestro which would have made my life much easier).
 
I just bought a Kenwood receiver with a RCA input for backup camera. The Sienna, of course, has a bunch of wire harnesses and no RCA cables. I looked at a bunch of threads here and on TN and it seems that my best bet is to find the video+ and video- wires from one of the stock wire harnesses and cut them and solder them onto a RCA plug. And then connect the receiver's backup wire to the backup trigger wire on one of the stock wire harnesses. The question is, which wires do I use? I saw a thread on TN that mentions that you can use the #3, 15, and 16 plugs on the harness, but I looked at my stock wire harnesses and none of them have 16 plugs, so not sure if that's referring to a stock harness or not.

Anyone have any info that could help me figure which wires to connect to a RCA plug to use my stock camera?

edit: here's a photo of the wiring schematic from the Toyota tech website that seems to show the wiring for the backup camera. Is this correct? So I should look for a harness with 3 wires (red, black, white) and connect the black wire (V+) to the RCA core wire, the white (V-) wire to the RCA shield, and the red wire to the backup trigger? Only problem is that when I looked at all the wire harnesses connected to the stock stereo, none of them have only those wires (there are three harnesses with other wires in addition to white, red, and black).

Is there anywhere that I can get a specific harness pin layout of the wires?

Where did you find this diagram, I'm looking for one that is for a non jbl/nav unit and the small screen above the radio
 
This may not be the right place to piggy-back on this thread, but after reading through this thread over the past week or so I attempted to tap into the small display (non-navigation) on my 2013 Sienna to connect the factory backup camera to our new JVC head unit. I chose this as my first soldering attempt, and it went very poorly if I'm being honest :) I've since re-soldered the connections and everything looks serviceable, but in the meantime the van has just gone bonkers. The windows and doors stopped working as well as the backup camera on the small display and I never did get it to work on the JVC. I'm fine with not getting it to work on the JVC (maybe some day I'll try again) but I'd like to at least restore functionality on the small screen. When I put the car in reverse, nothing happens, which makes me think that either I damaged the reverse circuit in some manner by my hatchet soldering job, or that perhaps I blew a fuse somewhere that is causing the reverse circuit monitor wire to not sense that the car is in reverse. I checked the fuse box diagram and nothing really looks like it would apply, but wondering if anyone has any ideas... oh, and incidentally, I am pretty confident the windows and doors not working are due to me disconnecting the battery, as the windows do work if I use the switch on their own door, just not the switch on the driver's door. Suggestions welcome!

FYI, I was able to fix everything today...thanks to the local regional library having access to Chilton's manuals online I went through the diagnosis and tracked down that the reverse lights weren't coming on either; reverse lights weren't coming on which meant that the monitor wasn't getting a signal that the car was in reverse either. Didn't make sense that the park/neutral switch had gone bad, so finally was able to track down the fuse (#5 inside the van) that blew when I borked the wires badly enough that it blew the fuse. Replaced the fuse and the camera came right back on. Windows and doors were just wonky because the battery was disconnected; searched the forum and found the answers on how to reprogram the doors and windows to open, so all is well again.

I got it from the Toyota Tech website which costs $15 for 3 days access I think. Worth it to get what you really need and can't find otherwise though. Good luck!

Damn, nice job! I truly hate/dread troubleshooting car stuff so it's pretty cool that you figured it all out and resolved the issue.
