My car, 2007 RAV4 with B9004 sat nav:
I have a camera already installed (previous owner had a reverse mirror setup), made a wiring diagram and thought I´d have everything working by tonight.
I took the panel off the rear door expecting to find the S7 connector and there was no connector! Am I looking in the wrong place (see photo).
So if I can´t start at the missing S7 connector in the rear door can I start at the rear of the B9004 sat nav and work my way back to the camera

The camera is mounted next to the number plate light and came with the cable already ( permanently ) connected to the camera therefore there is no connector in the rear door. Could your's be this sort of installation?

See Attached file. If I remember correctly (and it's quite a few years since I investigated this) looking @ the picture, if there, it will be to the right and it's between the inner & outer door skins. Just behind the skin that the moisture sheet is attached to. It can be easily overlooked.
Is it possible your vehicle had a sat nav upgrade? Some of the lower model vehicles (at least UK-wise), did not have the harness there.
Although the majority of the wiring harness is unlikely to be different, we can only account for UK models. (would have been XT5 and T180 in this case).
It can still be done without the harness. You just have to run your own and know what you are doing at the satnav end.

Hi shcm, thank you for your help, before I refitted the cover last night I carefully followed the loom that comes through from the car into the door, I followed the wires all the way to the wiper, stop light, door lock and noise reduction filter, unfortunatly there are no other wires comeing out of the loom...... (but I will check again because there's always hope). I now need a diagram of the rear connections for the B9004 so I can start from that end.

see attached file AS-NS.pdf (54.02 KB) pins 21 to 24. If you're not sure which end is which for the connector, use the wire colours in the pdf as a guide to work it out.
For the camera power supply, the head unit supplies 6V to the Toyota camera. You may get away with using that or you may not or it may be unreliable. It all depends what and how smart the voltage regulation is in after-market camera. It will probably be regulated to 3V3 or less internally in the camera and 2.7V (6V-3.3V) is more than enough headroom for a linear regulator (assuming it's linear). However, there may be a deliberate "under-voltage" cut off present or a higher internal camera supply may be required. Best to stick to what supply the camera spec specifies (usually a nominal 12V for after-market) unless you have electronics expertise.
Also be aware that the state of the back door switch (BTCY) input to the headunit can also affect whether any camera picture is displayed or not, but it should notify you of that on the screen.
Good luck.

Thanks for that shcm, this morning I removed the trim again just to check.... the connector is 100% not there I´m guessing the diagram shows the rear view of a plug/connector that goes into the rear of the B9004 unit?
Seeing most if not all non-Toyota cameras are 12 volt, I´m hoping that all I need to connect at the back of the unit is the two video in pins 23 (V-) and 22 (V+). I´m no expert but I guess when the B9004 unit picks up a video signal on pins 22 & 23 it would stop whatever is showing and show the signal on 22/23 (I hope it is as simple as that!).
I would take 12 volts to run the camera from the backing light and earth the camera at a normal earth point.
I´m not too worried about the back door, I think that as long as the rear door is closed the camera would work fine.
Unless I´ve missed something, this is probably the simplest way of doing it that I can think of........
So, have I missed anything above?
cheers, John

I´m guessing the diagram shows the rear view of a plug/connector that goes into the rear of the B9004 unit? Yes, see the PDF. It's connector E54(D) which is 24 pin. Seeing most if not all non-Toyota cameras are 12 volt, I´m hoping that all I need to connect at the back of the unit is the two video in pins 23 (V-) and 22 (V+). I´m no expert but I guess when the B9004 unit picks up a video signal on pins 22 & 23 it would stop whatever is showing and show the signal on 22/23 (I hope it is as simple as that!). No, it only works in reverse. i.e. it needs to see the reversing signal select too. E57(E) pin 5 of a 5 pin connector. Very probably already present, because of the vehicle speed signal is carried on the same connector. (needed for navi position dead-reckoning when GPS signals are lost e.g. in a tunnel/heavy built up area). see pdf for all of this. Read this carefully: forum.rav4driversclub.com/thread/76/rav4-rear-camera-installation-update V- should also be connected to CGNDIt may work intermittently or not at all without that. Otherwise V- floats and there is not a good reference for the negative going video sync pulse on V+. I believe Toyota cameras pull V- to GND/Chassis when the camera is present.

Hi,
first shcm, thanks for helping me and putting up with my lack of knowledge!
Just a couple of simple questions about your previous post....
When you say "it needs to see the reversing signal select too", what signal would that be? (to pin 5 of the E57 connector). Can that be + 12 volt from the backing lamp?
If I find that the connection to the back door courtesy light is needed, (to pin 5 in the E54 connector) Would that be pos + 12 Volts from the switch that turns on the lamp when the door is opened?
I hpoe I´m getting closer to a solution, thanks in advance!
cheers, John

Hopefully the reversing signal will already be there, but yes, otherwise it's 12V from a reversing lamp or the reversing lamp switch. In my opinion, the thing to do now, before anything else, is to take the head unit out, to see what you are really dealing with. (Get a trim tool and a nice soft thick microfibre to protect the dash from sharp metal brackets on the head-unit, when the head-unit gets pulled forward. The silver panels each side of the head unit lever up from the bottom, relatively easily from their clips. Disconnect the two switches, throw the trim into the back seat and you have access to the head unit bolts). Now have a look at the connectors and the wires going to them on the back of the head unit (or take a picture & post it). From this and the wire colours in the pdfs I've posted, you should be able to work out what signal connections are present. The rev signal is on a 5 pin connector (usually grey or black connector shell, I think). You can also see whether the 4 camera wires are populated in E54. If they are, you may be in luck, as the camera harness connections may still be lurking in the rear somewhere. If the 4 cam wires are not present, you're going to run into the next problem........You're probably going to need connector crimps (because you can't really bodge the camera connections and still keep the other signals on the same connector connected. For example, the telephone mic shares the same connector).
Secondly, you usually can't just insert the crimps into the shell. If I remember correctly the connector is one of the secondary locking mechanism types. If you look closely, there's a separate plastic piece that's part of the connector shell, but flush with the top surface. That needs to be carefully pulled up (with a small flat blade screwdriver, don't try and force it out completely) before new crimps can be inserted easily. ....this is why we tend to tell people to go for the connector in the rear door......... If you get this far, I'll try & look up the crimp part numbers. If you should disconnect the head unit completely, it will need the DVD in to reboot, once reconnected. It will remember some settings after being disconnected from its permanent battery feed, but not all.

OK, the very latest news......
I took the head unit out (a very easy job) and found that on the E54 there were no crimps or wires in positions 1, 21, 22,23 or 24, so there is the very good reason why there was no camera connector inside the rear door
If I had the correct crimps I could do something, (maybe you CAN find the correct P/N shcn) ... I will go to the local Toyota dealer tomorrow, they have gotten used to me and my strange questions!
By the way, the diagram of the E54 connector shows it from the ´front´ (the end that goes into the unit).
cheers, John

The Toyota connectors are almost identical (they may even be the same) as Tyco multilock 025 series. I have used Tyco 025 12 way shells (plugs) in Toyota 12 way sockets. The most readily available 24 way shells (plugs) in this series have a slightly different keying arrangement to Toyota's 24 way (90980-12404). The female crimps for the 025 series are these:
(or tyco part number 1123343-1) if you can find them elsewhere.
I'm making no claims they will work, but I've used them in the past. It's up to you. You might get crimps from Toyota, but you generally wouldn't in the UK. You might get a connector with pig tails from them, but usually £££££. They generally deal in wiring kits.
So that the analogue video signal from the camera doesn't degrade, ideally you'll need 75ohm coax for the video or screened cable at the very least. (There is a cable screen shown on the diagram).

By the way, these click in from the rear of the housing I presume?
Yes, but only after the locking insert (secondary lock) has been lifted (about 1mm), as I mentioned above.

Great, now I´ll look for a decent camera so my time is not wasted.
I will probably mount it at the top/centre inside the rear window, I tow a trailer often to our cabin, if a camera was as low as one mounted just above the number plate that would be useless.

I remember this type of pin now, I had 8 years in the R&D Dep. at VDO Australia years ago and made the instrument clusters for Ford, GM, Nissan & Toyota, all by hand..... completely different now of course!
