For those of you with trailer camera ports on your trucks.  Those GM accessory cameras are $400.  Here is how to make poor man's accessory trailer camera.  I made mine for about $130 dollars.  Attached is a pic of my invisible trailer working.  You can customize your length of wire too unlike the gm one.

6. 3/4 inch PVC pipe

7. Epoxy Glue

8. Wire conduit

9. Electrical tape

 

Steps 

1.  Drill a hole in the mount bracket so the camera connector port with fit in a way where you can epoxy glue the camera to the mount.

2.  Epoxy glue camera to the mount bracket.

3.  Cut casing in half and drill a hole in the thick side for the camera lens to fit in.  Use another half piece as a cover for the back.  You can epoxy glue these onto the mount or use a thin long screw and nut to connect 2 casing shells.

4. Connect camera wire, cover wire with wire conduit and electrical tape and run line using adhesive tape and ties to hold up.

5.  On the truck end of the camera you will can make a plug end over to slide over top the DVB plug end with PVC pipe.  I put the DVB plug inside a PCV pipe and epoxy glued the back side in.  I dremmeled 2 slits in the PVC pipe so connector would fit in port(see pictures)

Thanks for the model of the plug. Could you provide the .stp? My F360 instance wont take a .ipt as it is the Personal version of F360. I was able to design a camera housing but nothing for cable yet a

Thank you for this!  Immensely helpful.  Were you able to simply plug the camera in and the trailering app recognized it?

So you have to have max trailering package right? Like the options for these cameras on your display are already set up?

Yes it recognized immediately for rear trailer viewas shown in picture.  For the invisible trailer you need to drive slow in strait line for about a minute to calibrate camera as you do with $400 camera.  If you take it apart the $400 trailer cam that gm sells inside you will find camera I used.

Max trailering package is a different rear gear, heavy springs, a bigger diameter axle nothing with cameras.  I do not have max trailering.  I had the UVI package there is a camera in my high mount brake light for bedview and I had camera ports in my rear bumper.  I had options for hitch view, bed view, inside trailer view, behind trailer view and rear view.  I retrofitted the to UVS package which is  UVI  package plus 360 view and invisible trailer.

Rally6.2RST you seem to have a good electronics knowledge. I just bought a new 2022 GMC 3500 Denali. I already have two cameras on the back of my 5th wheel (one up at roof and one at bumper) that use a BNC cable (male at both ends). I previously had an aftermarket monitor that I hung on my rearview mirror. I know the 5th wheel is not compatible with the invisible trailer which I am fine with, just like having the cameras back there. I would prefer not to run new cables since I had to fish them through my back wall. Do you think it would work if I adapt the GM 23390514 cameras to my existing BNC cable or would there be an issue with the cables? I would need short adapter cables listed below to make it work.

Hello, I just came across your write up. Awesome job, but I'm hoping you can help. I ordered the exact same cable setup (I think) and where the plug attaches to the truck, the inner insert fits perfectly but the outer metal sleeve (with the 4 slits) is larger than the male side of the truck plug. Is yours the same way? Does that need to touch for ground wire or complete the video signal? I plugged it in and hit the inner camera button on the screen and its showing no camera attached. I have a 2020 Silverado with advanced trailering package. So it should just work

Thanks for this post. Question, I have a 42' 5th wheel and 2023 Silverado 3500 on order. I understand the transparent trailer view won't work, but can you use either the rear camera view or the pic in a pic side view, correct?

This is cool!  Does the trailer view stay on while driving to act as a rear view mirror or do you have to select it in 5 second interval?

This is fantastic! Awesome write up. I will be doing this soon. One thing I would like to try is adding an analog video switcher such as this. The reason is so I could have the exterior rear trailer cam and the 2 interior, cams and switch the source accordingly for the interior cams in the single interior cam port on the bumper. Of course I would need the DVB-TV to RCA for the splitter. One reason I think this might not work is the GM cameras seem to get power and video line all on the single DVB-T to Fakra A cable. If i were to add a splitter inline it may kill the feed entirely as the power might not pass through as expected. None the less, the switcher is cheap enough and so would the adapter cables to test.

 

On another not I plan to design a 3d Printed mount for the cameras. I can provide the .stl files once I figure it all out. 

 

Again thanks for the write up.

It's not an analog signal any longer, these cameras operate on TI FPD Link III and it's a pretty sensitive protocol. Signal integrity and impedance matching is very important.

It would work with a BNC cable but as I said in the post above, it's not analog 75ohm style camera system. 

It's a 50ohm impedance system so if your wire was 75ohm it will have to be re-ran.

Okay that was my other thought that it was not analog. Thanks for the information. More research will be done on the TI FPD Link III to see if something can be bought to have 2 inputs with 1 output.

Luckily i have not bought or ran anything yet as i just found this thread. I will make sure to purchase 50ohm RG316 cable with proper ends. At the end of the day, if i cant have two interior cameras it is not the end of the world. I will at least have 1 interior and 1 exterior with this solution. 

 

Thanks for the additional information!

      Factory front brake rotors...defect?

      By Chris80s · Posted

      On my wife's 2020 Blazer (~69000 miles), we started to notice the brakes pulsating at faster speeds. Typically around town you don't notice anything, but highway/interstate driving you will notice it. I decided to pull of the front tires and look at the brakes. I figured with the milage, the pads should be wearing out to their life span, but they actually looked decent. Still with "meat" on them. One pad has a ridge wearing in it, and that same rotor is showing the ridge too. That's not the concerning part...the other rotor appears to have a raised bump on it!  The picture make it look like a pimple! Very odd and strange! NOTE: These are the factory brakes and rotors.   I'm attaching pictures of the front brakes and what they look like ate ~69000 miles.

      Remote Start Noise 2024 2500 HD Gas

      By BCGM · Posted

      2024 Chevrolet 2500 HD Custom 6.6 Gas Canadian built Truck  I tried to search for my previous thread on this topic but cant find it so my apoligies  for starting another one    #1   Since we have owned our truck purchased new it has this strange noise after using the remote start function  you press the remote start and you hear it start but right at the end of it starting it almost seems like it wants to start again after the truck is running .   There is no gap in time it is right at the end of the start . Almost sounds like when you have started a car/truck and its running and then you try and start it again and you get that grinding noise ,sort of     #2  You can only hear this if you are standing outside of the truck and near the truck  you cant hear it when you start the truck from inside  the cab . So it may very well be happening when starting the truck that way as in normally    #3   This only happens when it is started after sitting . For how long I don't know but it happens after sitting overnight for sure and it wont do it if you stop the engine after starting and then start it again  I have had it in to the Dealership before concerning this but they did not have the truck  when it was cold to hear it . Now its back in the Dealership left it overnight so they could possibly hear the problem . They said they tried and nothing happened . Well they did not know what they were listening for . I started the truck remotely and BINGO it makes the noise . Oh that sounds weird they say . We need to look into it ! I have left for this week at the Dealership    Does your 2024 2500 HD gas do this ?  Any of you fellas care to take the time and trouble to film this operation from a cold start  so I can hear what your sound like  Really  would like to know if this is anormal sound  Thank You Fellas !!

      2026 Z71 Forward and Rear Park Assist help

      By Slow · Posted

      2026 Z71.  The other day I was backing a trailer into the barn.  The alarm was going off just because the trailer was in the field of the warning sensors when you get too close to something.  For some reason now the warning alarm doesn't work anymore.  It used to go off when I was just normally backing my truck into garage.  I still have the guidelines in the back up camera.  Is there a button or something to push to turn the sound/Alarm on and off?  I have the touch screen in this truck.  There isn't a "P" on the dash except for the parking brake.  I can't find anything in the touch screen under settings or vehicle.  Thank you in advance.

      Post Pics of your "Other" Rides

      Well one of our most reliable vehicles was sold yesterday. The first and only I gave for free to a grandkid. If they got skin in the game they take care of it. My wife bought new. Five years later my daughter got it to use. We got it back and gave it to our grandson after graduation. He did zero maintenance just oil changes. When the AC quit he drove his mother’s car rather than get it fixed. Instead he just bought a beater and sold the Elantra.

      OCI, not when but why?

      By KARNUT · Posted

      I usually do as well or better than the sticker for mileage. Usually better going west than east. North then South. Wind makes a difference. I’m not usually a conspiracy theorist. But it did dawn on me I’m going by the vehicle calculation. Now that would be interesting.
