Looks like a smidge over 1/2” which is also the same as the cord wrap.

Looks like the tar tape / heat shrink and the sleeve can be removed, there is also a possibility that the corrugated sleeve can also be removed. I see this is almost possible to pull thru a 1/2 EMT tubing with poly-water lubrication on my trailer. So not all hope is lost. Thank you very much for taking your time to get these photos.

I agree you could probably remove the tape etc and I’m

assuming the cord inside the corrugated Is shielded too.

happy to take more (better) pics if you need

I have not yet looked into this per my prior post, but if this is indeed triaxial then that would allow for the camera bias voltage on one wire, the video on another, and the ground common to both perhaps as the outside shield. Triax is not all that difficult to deal with, just 3 conductors instead of two. Coax video typically has the video signal in the middle shielded with a ground outside wrap. These are also impedance sensitive and are usually 50 ohm or 75 ohm.

My suspicion on the triax connection needs to be verified but that would be easier for Chevy to implement a camera bias as well as a video signal with a common ground. I am assuming that the camera is isolated and does not need a trailer ground to work. Many trailers are fiberglass shell, and as such not conductive, so you would have to run a ground wire to the camera if the mount depends on a trailer ground.

I also have another question... Where do all the video camera connections come into the dash display? Is it behind the dash, or perhaps on the truck computer somewhere. There are numerous cameras on the truck, so those video feeds have to go somewhere.

I am curious as this may be a point to feed the wireless video from my Furrion camera to the truck, and bypass the rear connector altogether. I still want a wireless solution. I really want to be able to use my Furrion camera as it works at night too. Such an oversight on Chevy's part.

OK, so I have a 2020 Chevy 3500HD. I do not like having to string a cable from the rear of my 34' trailer to use the camera option. From my understanding, the cable has a DC bias for the camera with the video riding on this voltage. This allows one coax cable to supply both the video and the DC needed to bias the camera. I currently have a Furrion wireless camera mounted on the back of my trailer. I am hopeful at some point a wireless adapter will be made that could plug into the camera plug on the bumper and talk to the camera, sans the cable. Not sure why a wireless camera is such a problem on a truck that has wifi, bluetooth, satellite, and can be a cell hot spot. Seems it should have been wireless from inception. My wireless Furrion rear trailer camera has been around for years. What a concept.

However, I am an electrical engineer, so I am thinking the following in the absence of a commercially available solution...

This is video signal we are trying to get to the camera plug. I may open up my little monitor that came with my Furrion wireless camera and see if I can add a video connection where it connects to the monitor and bring that video out to a plug I can deal with. The monitor does not have a video out (it's built in to the monitor), so I am essentially making a video out. This will keep the camera wireless, and I do not have to buy another camera. The Furrion was about $350 too. But wireless and works at night. The mount came on my trailer (Grand Designs Reflection) and included the 12V needed for camera bias (I added a switch because the 12 volt camera bias wire is always hot, keeping the camera on all the time).

I haven't measured the DC voltage at the camera plug on the bumper of the truck yet. I would suspect 12 volts, but Chevy may have this a different voltage. By adding a simple filter on this plug connection, I could block the DC and pass the video. This would allow me to make a short cable from the wireless monitor with the new video out to the camera plug. I may find the camera coax in the truck's wire harness and bypass the camera plug on the bumper altogether. Anyway, this will likely be a winter project. I will post if I get it working.

I agree with the prior posts that paying $350+ for a GM camera system that does not have IR for night vision is a shortfall. Such an easy addition. And having to string a wire is also a shortfall. In fact, Chevy could have simply made their trucks compatible with the Furrion wireless cameras already widely available and in use on trailers and this could seamlessly interface to the truck video computer system, and wirelessly, and syncing just like the Furrion camera already does to its monitor. But that would have been way too easy. Come on GM engineers, get with the program. This is not rocket science. You could still charge us customers by making this option something you would have to pay the dealer to enable (an electronic key of sorts).

EE to EE, bypass the bumper connector and you will see what plugs into the trailer/camera connector and all will make sense.TRIAX connector with BNC ends that carry SDI. unlimited options of ability to convert signal to whatever signal carrying you like. BNC to cat5 or a/d converter the options of customizing are endless.the signal is SDI, The issue I have yet to discover without more testing is these cameras gm has on the trucks. I think they are higher resolution (hd so they call them) but that is being cleaned and filtered at higher resolution at wherever they are plugged into. More time and testing will tell but the GM camera seems nothing special, a $10 camera at best.

Thanks for the input Christopher. As I said, my goal here is to get to a wireless solution. And hopefully in the process end up with a camera that has some night vision capability as well. I am really hopefully I can adapt my Furrion wireless camera that is already on the back of my trailer to the truck somehow. SDI carries audio too, but I don't care about that aspect of it. Just the video.

It would seem logical that Chevy would be developing a wireless solution, or perhaps some other aftermarket camera maker (Furrion?) may work on it. The problem is that so far only Chevy is doing this (that I know of), so the market is limited. I am not sure yet what the video is in the Furrion monitor that is the other half of my camera system. Since it is winter and I am not camping much, this may be my opportunity to open up the monitor and see what is there.

I am also hoping for some input on this forum on the video connection within the truck (e.g. where are they?). I really do not want to take much apart on the new truck without knowing if I am going the right direction.

hptulsa · December 6, 2019

i probably missed this in the discussion but are you trying to connect your furrion to the truck so the picture comes up on the trucks screen like the other cameras do?

After using my interior trailer camera (the GMC version) i've concluded it is not what i am looking for...this camera only comes on when you select it from the screen and only stays on for 8 seconds, then defaults back to the radio or other screen. If you are going less than about 10mph, it stays on. I haven't used the camera (or port) that is for the rear of the trailer, but i suspect it only comes on when selected. I am now just going to use an old ipad (set up in the dashboard tray) and a bluetooth/wifi hotspot-peer-to-peer battery powered wireless camera (Blink system is my first attempt as the battery life is very good).

I will experiment with the rear trailer camera to see if it can be selected to stay on or at least until you deselect it...

Just my observation. The GM camera that I added to the back of the trailer under the Rear View Safety camera Stays on all the time and doesn't time out. I have it mounted a lot higher than I guess is recommended as I have never been able to get it to program for the invisible trailer view. When I select that view it shows the camera in a rectangle box in the middle of the other cameras but If I select full screen it is very sharp. A lot sharper than my Rear View Safety camera but the Rear View safety camera is several years old and they are both hard wired to the truck connections.

I like the system so far. Just wish the trailer TPMS would show on the screen with the Truck TPMS without going through the trailer screens.

Anyone know anything about this 2.4 wireless Gm camera? Seems half the battle would be finding what module it communicates with and then if it’s able to be fed into the current trucks. I would say it is not 1080 So that would be a whole other issue. I see many 1080 cameras out there with IR and think one could take one, cut the end off and put the triaxial BNC connector on it and plug right in for half the cost. Any objections? I’m just not seeing the cost vs quality for the Intellihaul camera from gm

The VPM, video processing module, is located behind the passengers seat back(second row seat on double and crew). You have to remove the seat back to access it.

This has been a past issue also that the company MVI has worked out in the past to allow the camera to stay on without the timer. This is reprogramming of the control module and will most likely being addressed by them as we speak. it seems the first thing we need to do is get affordable 1080 camera with IR able to be plugged into the rear bumper ports. I think sending the signal wireless isn't an issue if an affordable camera is used there are many wireless ways to send the signal and then pick it back up and send it to the connector at the bumper plug. In your case we will have to wait and see when they are going to take care of the timer issue.

Perfect info. That’s what we needed to know. That should allow us to use any IR HD 1080 camera and patch in wireless converters or send signal allowing the user to select which camera they want to operate. I’m happy to see them upgrading to HD cameras.

Made my 2nd rookie mistake pulling my new horse trailer! Used cable ties to secure the camera cable to the underside of the gooseneck to drape then down directly to the bumper connector...didn't think to measure that length when doing a wide turn! yanked both connectors from the cord (connectors still in the bumper!). So, now i have pics to show and looking for advice on how to reconnect if possible (seems similar to tv coax)...

connector Amphenol 31-14693 is stamped on connector.,..

Christopher Murphy · December 16, 2019

Oh no! Well you will need to get a new connector and install on your wire. Shouldn’t be difficult if you have the right tool. Amazon has a lot of special electrical connector crimpers that work great. Can’t thank you enough for the part number. That will help a lot of us out with making our own cameras.

Gecko50 · December 17, 2019

I am also curious what the main cable looks like. Under the corrugated tube and further back than the heat shrink tubing. I did a simple search and I could not find that part number. I also do not see any shielding as many has assumed? Is the white core a foam core found on many coax cables. Would you or could you take off the corrugated tube and heat shrink. That may also reveal the cable type with markings. How much damage was done to the truck side of the plug. If you do remove the covering please take a measurement on the diameter.

Thanks
