Thanks. But that's connection to APIM and for me it works ok. The problem is BCM that doesn't fit in (for the LIN connection; I have installed OEM camera). You think that the pins are equal?

Somehow yes. You can try to use a pin from any popular 0.1 inch raster computer connectors. Look for old CD-ROM connector:

It is better to put the pin when the connector is in place.

Firstly thanks for the great guide.
I’ve recently retrofitted the OEM camera and wired as per the diagram Piotr shared, coded the APIM for rear camera, yet I don’t get the lines (not dynamic nor static). I’ve tried a few iterations including wiring only the camera into BCM pin 59 and splicing it into the existing wire in 59, as well as with/without coding the BCM for rear camera and checked the APIM coding 7D0-01-01 *A**

Now I’m a bit stumped, every guide I’ve read says this should be working.
 

car is mk4 focus titanium with PDC front and rear, lane keeping assist, collision warning etc.  

Also to add to your guide, you can order the pins from mouser or similar with the following part numbers: 

APIM: 1924955-1

BCM and camera connector: 2035334-3 or -6

They're all made by TE 

BdyCM (BCM) coding:

726-17-01 xxx8 xx

or just find "Reverse Camera" in explicit configuration. 

One important thing, following the configuration it is needed to execute BdyCM procedure "Test Module Communication"  (or something sounds similar). This step is critical.

Thanks for the reply, looks like it’s called “local interconnect network new module calibration” which states it’s for new modules such as the camera, but I keep getting the error message at 8% “test aborted, perform self test to identify any DTCs” which only brings up a code for battery backed sounder. 

edit: it never worked but I did a BCM reset and the camera is now working 🤷🏻‍♂️

New information

Hi @piotrmod or anyone knowledgeable in this area,

I'm relatively new to retrofitting, and I'm currently in the process of adding an OEM camera to my MK4 Ford Focus.

I'm hoping to purchase the camera model jx7t-19g490-ab (or any other camera shippable to Portugal), but I'm a bit unsure about the necessary wiring components.

Could someone point me in the right direction regarding which wires I need to buy for this installation? Any helpful links would be appreciated.

Additionally, I'm wondering if this camera requires a 54-pin APIM adapter and an RCA cable. Could someone clarify this for me?

As a beginner in this field, I'd also appreciate any additional tips or advice that experienced members might have for a successful retrofitting process.

 

Many thanks in advance!

You have prompted me to post a write up I did last year, but never got round to publishing.

Hopefully it may be of some help to future installers.

My Installation

I've just completed my OEM camera installation and I thought I would share some details of it, which may assist future installers.

And a big thanks to Rickychips and the other pioneers of Mk4 reversing camera installs, whether OE or aftermarket.

My approach was to start at the tailgate (Estate), install the camera and wiring loom as far as a new 6 pin male molex connector (off Ebay) just out of the left hand tailgate rubber cable duct and tucked above the roof lining.
Before I wired up the molex I connected the loom tails to a 12v suppy and a mini-monitor to check it was working OK - it was, except the picture was black and white as the monitor was PAL and the camera NTSC.

Next I did the APIM and BCM wiring plus ignition 12v from the fusebox. I followed Piotr's keyhole surgery approach to getting access to the APIM.

I made the 3 wires into a loom and ran it in the left hand sill cable tray and eventually up to the molex connector I had previously installed in the roof. I put the female connector on, joined up, did the Forscan mod and I was up and running!

A few more details: you will need a 10m length of two core screened cable. I went with this one
https://www.aliexpress.com/item/33048879036.html?spm=a2g0o.order_list.order_list_main.29.21ef1802x1CO74
in 24awg, mesh screen, flame retardant. Avoid CCA cables.
For the BCM and +12v I used single stranded wire, 1.6mm od.
A roll of fabric loom tape is useful for a neat installation.
For the camera and apim connectors I didn't have a suitable crimper, so I soldered the pins. You need to cut down the "wings" of the solder area after soldering so they don't foul the shell. And be sure to use tails of narrow gauge wire as there's not much room, especially in the camera connector.

Tailgate

I had trouble getting the plastic trim panel off the tailgate - every single one of the yellow plastic rivets stayed in the metal of the tailgate. What a bad design! In contrast to the Mk3 where the panel comes off relatively easily. In fact the whole of the installation was somewhat blighted by these plastic rivets of varying colours and other plastic clips, all of which are keen to break as soon as you look at them.
Once I got the panel off, I took the old tailgate switch out - take care, the clips break easily; you can release 3 from inside and I managed to release the back one from outside with a plastic pry tool.
Then I fitted the new switch with camera and made up a loom to reach just outside the tailgate. I routed this up the left side of the tailgate, following the existing loom. Since you are working upside down, I found it helpful to attach the new loom with twist ties first and then use tie wraps.
Getting the wiring through the flexible duct was tricky, as the wire ends get stuck on the corrugations. In the end I resorted to the vacuum cleaner and dental floss technique - it worked like a dream.

Body Wiring Front to Back

I found this fiddly, with lots more of those trim clips very eager to break. If doing this again, I would be tempted to route the wiring up the left hand windscreen pillar and go back above the roof lining. The light fittings could be useful "break points".

The genuine camera is not using RCA signal. It is "symmetrical" or "differential" signal. All the RCA adapters simply bind negative line of the APIM input to ground, letting out only positive signal as the RCA core. This can work but loses the key benefit from the "differential" line - immunity on disturbance. So, the proper connection of the genuine camera requires both lines V+/V- and ground (shield) signal to be "retrofitted" on the 54 APIM connector:

Hi. Thank for the guide. I have a doubt, this guide is the same for automatic gearbox?

Directly from the camera to BCM:

Dear Piotr, first of all, thank you for your support and guide.

 

If i understand well, 

if I understand correctly, you have to buy a camera connector and bring the wires from the camera to the c405 connector on the car.

Then a cable directly to the bcm.

What is not clear to me is how to connect to the apim, can you describe this procedure to me?

Thank you for your precious support

Actually, all has been already discussed here. I have also post a photo of my way to get to the APIM connector. You need to use double shielded cable (two wires in shield) and connect them as it was described herein. The BCM connection is somehow the same story, need to add a pin. Without BCM connection, there will be no steering lines and magnify feature. So, adding OEM camer makes sense only if we add and enable BCM connection.

thanks for the reply. 

Forgive me if I return to topics that may have already been discussed. But for me these are complex topics and I would like to be sure.

From what I've seen, you get to the apim by removing the part with the air conditioning vents, but where do the cables coming from the camera enter apim?

Hi,

Can we get the matter of cables sorted? It seems a bit strange how there is a cable of 10m and others of 1.6m.

Camera <-> APIM ( 2 core, shielded - 5m, 24 awg? )
Camera <-> C405 ( Power -> "Simple" 2m, 22 awg? )
Camera <-> BCM ( shielded - 4m, 22 awg? )

If there is no PDC, needing F3 (BCM) <-> Camera ( Power -> "Simple" 4m, 22 awg ? )

From the glove box side

Is difficult to get to c405? Do you need to dismantle part of the sky?

Hello!

There was one thing missing when retrofitting OEM cameras: wide view. Finally, I have nailed it down!

So, if you don't have this button:

you need to do two things:

1) In APIM, set "Rear Camera Split View (without multiple cameras)" (I'm not sure about English translation, something like this anyway), this reflects bit: 7D0-02-03  2xxx xxxx xx

2) Set LIN configuration in BdyCM for RVC (Rear View Camera). I don't know why cars with RVC has different values in it. I just found a car close to mine and copied values. In my case:  726-15-02 xx6F xxxx xx

3) Execute already known procedure "Testing Module Communication" in BdyCM.

Done!

BTW: It should be camera, which has number ending with -AB. In the Ford data base, there is only -AB camera for MK4.

 

Great, the split rear camera view works, but I still have problems with lines. They just don't want to show up.

Can you send me please your VIN, actual BdyCM asbuild and APIM asbuild data? Just to be sure, camera ending is -AB?  I was analysing lot of asbuild data and maybe I'll find some discrepancies.

Interesting! Good work, Piotr.

Currently I have a "+" button in top left corner of reversing camera screen. If I press it I get a vey narrow angled view from the camera.

Does your mod replace the + button with the wide view button, or is it the case that if I have the + button, then I can't get the wide view button?

9 hours ago, Albacore said:

... if I have the + button, then I can't get the wide view button?

Exactly, there should be two buttons. "+" button is a zoom, it just make a close up of the view. "Split" button divides on three parts and makes sides to be visible.

Thanks Piotr. I'm not a Forscan expert, so could do with a bit of help.

I've found the Apim setting for the rear camera split view. I also found a text setting in BdyCM for enable rear camera, which was disabled. I tried enabling both, but I didn't get the split view button and in fact the "+" button just made me loose the parking sensor view, so for now I have put both settings back as they were.

So presumably I need to change the BdyCM as built data?

Is this a case of finding 726-15-02 and changing digits 3 & 4: xx6F xxxx xx ?

And where is procedure "Testing Module Communication" in BdyCM?

Cheers,

Lance

Yes, you need to do all changes in APIM and BdyCM, but "Testing Module Communication" procedure is crucial. You will find it in the "wrench" section, here:

 

Thanks again. I've got it working now! The BdyCM mod did give me a warning about a checksum error, but it seems to have gone through OK....

I wonder what split view with multiple cameras is - sounds interesting. I always thought some side cameras would be useful!

Next week we will be getting a Ford Focus Wagon 1.5 182hp ST Line Business (2019) but it lacks automatic parking and reverse camera. Missing automatic parking does not bother me but the camera would be nice to have. So I came across this topic and what a lot of information!

I read almost everything and will be buying the wiring, connectors and camera. But which camera do I need to activate and user the dynamic lines? Most cameras are JX7B19B514BA and occasionally the JX7T19G490AB like mentioned by @piotrmod 

Btw did others got it to work, dynamic lines included?

Thanks in advance.
