Thanks for keeping this thread alive SlowJoe….What confuses me about my truck is I already had the wiring on the body harness with all the pins filled in the connector. Once I added the Jumper harness and CHMSL assembly the pins on the harness going to the CHMSL were all the same as the body main harness connector at the C-pillar. In theory, for my truck anyway, I should be able to just add the module, switch and bezel and be in business. Sounds good on paper, but my gut tells me it will be far more complicated.
I'm half tempted to just try and find a camera that will fit in the OE cameras spot on the CHMSL and run it off my CTS2. Im really trying not to do it this way as Im looking into possibly getting the Derringer and I don't want to add an OBD2 jumper and have all that stuff on my dash.

The quest continues...

 

Jerry,

Im no expert but I think what you would have to do is remove the camera wires from the main harness, and move them to the CHMSL area and get a camera that will work up there. I don't believe that the OE cameras for the gate and the stop lamp are the same, I will try and confirm that for you in the morning when I can get to the shop and look at my truck and search some part numbers.

Jerry;

There are a couple options and your thoughts of making a new harness and running into the cab an splicing in the camera works in theory.. A few things need to be confirmed to help determine how complicated or far you need to go on your setup (Your answers on your findings would help in this as well) I have not been able to open my truck up to confirm these either (weather and no garage does not help!!).

Need to confirm first;

1. Check your fuse box in the passenger kick panel. See if Fuse 34 is populated (in the owners manual it refers to Heated steering wheel, something else and Image processing unit) - This fuse feeds the camera power for the CHMSL.
2. Open up the C-pillar and connect the new harness and CHMSL. Disconnect the connector on the camera itself. Turn the Key on to the run position. Check the Pink colored wire in position 1 of the camera connector for 12 volts positive. This will let us know if indeed the dash harness is feeds power to the CHMSL (this makes what your after much easier).

If you can answer yes to both these questions for your XL series, I will be opening my XLT up and checking hopefully before I get away from this cold snowy weather and escape to a beach for unlimited tequila!! Also most of my parts should be here to start building my wiring harness.

If you were able to answer yes to both questions. The process gets fairly simple in theory and on paper ( I am an Electronics technician, so schematics and wiring are my niche)

If attempting either option please ensure you have someone perform this work who is intimately familiar with soldering in a vehicle environment, local stereo shop or remote starter shop.

Option one: (Power is at the Camera connector of CHMSL) There is a connector in the drives kick panel C263. You will need some two wire sheilded cable (Important to reduce noise on the video signal) pin location 17 (Shield of the shielded cable), 18 (Video -), and Pin 19 (Video +). Route this cable up behind the APIM (Sync 3) at the APIM. at this point you have two options splice the wires into to the existing feed or cut and splice and eliminate the rear tailgate camera completely for your purpose. (Not sure what you do with the trucks after you mile them out) The wires on the APIM connector are as follows Pin 14 (Video +), pin 15 (Video -), and pin 33 (shield, this wire does not need to be cut as it is an extra ground to prevent interference)

Option two: is to proceed with building an large extension cable to run from the back to inside the cab and splice into the CHMSL harness as you have eluded to. Knowing whether or not the factory harness has power at the CHMSL or not makes determining how your extension cable is built. No power you need all 5 wires, if not again the cable I mentioned before will be just fine. Just be sure to route it safely and securely along the factory wiring harness to keep it protected. Remeber this long cable run will give you a bigger chance of poor image on the camera. I don't have access to the camera connector pin out at the moment but can post if necessary later, also I would have to find the camera pin out at the tailgate as well to ensure to give you the correct information.

Hope this sheds some light onto your question.

When I was researching to add Bed lighting to my truck, good friend of my is a parts person at a ford dealership we spent about three hours one afternoon making notes and comparing notes on the wiring harness at the back of the truck. We discovered some harnesses used by ford are generic and are same across all wheel bases. for example the harness that feeds the back everything at the back of my truck is the same harness in a Platinum the difference is what is plugged in at the end of it. Blind spot, Led tail lights, Led spot light, bed lighting, etc. the only difference on my wheelbase is gas or diesel, So I am not surprised in the cab you found what you did.

When we purchased our truck, I jumped into it without investigating some of the extra features!! We also did not have plans on a fifth wheel, figured we would just be pulling a bumper pull. I got banned from ON-line shopping last summer when I purchased our fifth wheel.

Side note I have all my parts on order to implement the IMPB into my truck. I will also being using some tone and trace tools to see if I can find the wires in the main harness of the dash. fingers crossed they are.

My action plan once all my parts arrive (one is coming from China so it may not be here till beginning of april);
- build and interface IMPB into truck, with Tailgate Camera
- Interface CHMSL
- Auxiliary Camera Feed
- Finally and another topic Trailer TPMS (not possible if I can't get the Auxiliary camera working)

 

Slow Joe,

So you don't even have a tail gate camera then? If that's the case that would make sense as to why you don't have the body side connector with all the pins filled of the CHMSL.

I do have the tailgate camera. and sync3 in my truck currently. The image processing module intercepts the tailgate camera feed from the APIM and then allows you to switch between cameras. Hence the missing piece of the puzzle to have multiple cameras. I have a long list of items to confirm before I can layout and build the interface cable to add the IMPB into my truck. but I have confirmation adding the module is possible without having the factory connectors (Another forum adding 360 camera to late model F150, this is where the idea to adapt to the superduty without 360).

My plan in my head will be an extension cable for the APIM which is from Amazon modify it to get the existing tailgate camera and feed it to the IMPB and then the output from the IMPB will be fed back to the APIM, as shown in the diagrams from Ford.

Stage one other than making everything realize I have added the IMPB the existing camera should just work like nothing happened. in total 15 or 16 electrical connections to make this all work (6 of those just at the APIM, 2 at the brake controller, 2 at the BCM, and 3 in the drivers kick. Provided the CHMSL is powered by the factory fuse in location 36 (my truck has the fuse installed, but I haven't confirmed the wire is populated in the BCM connector itself.

Then it really should be a couple forscan changes to activate the CHMSL, and the onscreen buttons on the APIM

 

Opened my C-pillar this afternoon to I investigate and pin out of the connector. I discovered I am missing 5 wires in the center of the connector. Which are for the camera. Pin numbers of c3047 3, 4, 9, 10, 12. Looking atone of your earlier pictures Sarge I see you and arein the same boat. They would be grouped in the center and to the bottom of picture. So this meansmy plan for the splice, does not exist in the drivers kick panel. Just means a few more feet of cable. Good news my IMPB arrived today.

 

SloeJoe....you da man!! I can see what aftermarket does not resell the factory CHMSL camera with modified wiring harnes to add this to trucks that it did not come with. That camera now retails for over $600. I was told the $500 I paid is s sceemming deal. We added the Camera Source version to the 2017 I just retired. It provided its own wiring harness that that plugged into the tailgate camera connector and ran from the back to the CHMSL , The Camera was a in a housing that position under the CHMSL https://camera-source.com/automotive...ry-camera.html

I might reach out to them to get there advice on feeding from the tailgate camera....Video and Power or just Video??

Will report back what I find out.

Jerry;

They do have a few options for you, none that use the CHMSL you purchased. Sync 3 you mean the 8 inch touchscreen? if so look at this one from them, https://camera-source.com/automotive...ry-camera.html

Sarge and others we are going to have both running and I personally like look of the factory one over the one from camera source. I also want the ability to switch between the cameras from the touch screen.

 

Joe,

I may have to pull mine apart again, I could've sworn my truck had pins in that connector on the body side of the harness. I could be wrong, its been 3 years already.

Joe

I am attempting to go down the same rabbit trail as Sarge....but in my case, I am just trying to get a single camera to work. The factory camera was a tailgate which I remove and keep off the life of my use.....thus lose that camera. I plug the terminator in the empty plug and now it shows "camera not found....see dealer", I have a the HC3Z-13A613-D factory camera, plus the two harnesses mentioned above (where/what is the one that has all green blunt cut wires??)

Starting to wonder what will the APIM see when the factory harness are plugged in along with the camera. Will a camera signal make it to the APIM? IF not, my fall back is the run a custom cable from the tailgate camera plug by the spare tire up to the C-Pillar or Camera itself to cheat the truck to thinking the camera signal it sees at the tailgate connector is really from the CHMSL.

Sarge;

Thought I posted a picture with a yellow circle... the pins in question should be inside this yellow circle.

Jerry;

I noticed on the Camera source website they had a few different options. but we all seem to be in the same boat, prefer the factory approach.

 

Joe or anyone with the ability to look up connectors.....What is the connector that plugs directly into the camera on the CHMSL housing


and does someone have the wires callouts???



I have a company that will make the custom harness to go from the tailgate camera to the CHMSL for those of us with ONLY one camera and we want to ONLY have the CHMSL camera.

Thanks for any help
