2 more observations, it appears that there is a hex type of crimp made, which is common for coax. I also see it appears the ferrule appears to be threaded as it has a grip type exterior to assist in tightening without slipping on the connector. But why is the inside of the boot a small round metal, what was the mating part, was that lost on the cable destruction?

It looks like that is coaxial cable, not triaxial.

They could send power and signal on the same cable. Just like they do with Direct TV satellite dishes. It makes aftermarket cameras more difficult...

If you know any Ham Radio operators one of them could probably crimp or solder a different connector (maybe a SMA)?

You would need to do this on both the truck end and camera end.

Search for RG58 SMA connector on You Tube there is a video that shows how to install a crimp on connector if you have the Hex crimper.

If you were in Phoenix I could install the connectors in a few minutes, there is bound to be someone that could do it in your area.

When I have time I will see how much extra coax there is under the truck. If there’s a little slack it would be easy to cut the coax and put connectors on both ends. I could add a set of camera jacks in the bed for a fifth wheel or gooseneck.

I currently have a furrion wireless camera on the back of my fifth wheel with extra monitor.  Would love to be able to use the gmc screen so I wouldn't have to have an extra screen sitting there.  However the GMC camera is a "wired" camera.  How do you run the wiring from the back of your camping trailer to the plug without it looking cheesy?

i found a 'hole' at the front of my horse trailer where the manufacturer had run the wires for the brakes/lights.  There is a track all the way to the back of the trailer so i used it for my camera cable also...at the front, it drops directly down around the gooseneck hitch, so i cable clamped it backwards to just over the trucks connection.  CAUTION! i did not allow for a sharp turn of the gooseneck and the first time i did that the camera cables ripped out of the truck connection and i will have to get new connectors which have been difficult to find!! 

 

Could you also cable clamp the wiring underneath your trailer to the rear? i used self tapping metal screws and it was fairly easy...

I agree it looks like 'mini' coax and seems to have the same type of termination, but when i was researching the type of camera/connectors, i found a site that said the cameras were using triaxial.. i will look back to see if i can find that again.

I looked under my truck today.

The camera cable is RG-58, 50 ohm coax.

If I had damage to the connector I would just replace it with a compression F connector. Direct TV uses these outdoors in all US climate zones.

Put in a splitter and you can have jacks for your 5th wheel and on your bumper. I would cut off the camera plug and replace wi a F connector as well.

Not sure if this has been said but dealer ran my vin and this P/N 84876818 is what came up replaces 84580657.

WRONG. RG-58 is a standard in radio and GPS. we commonly use it in aircraft. Directv does NOT use this. They use RG-6 and sometimes RG-59 if the installer is lazy. In addition you cannot use a splitter in this application. If you listen to this guy your camera will be damaged at the least.

I didn’t say Direct TV uses RG59 or RG58. I said they use F-connectors...

 

They use RG6 because it is lower loss at the microwave frequencies they are using than RG59.

 

RG58 is 50 ohm RG59 is 75 ohm. At the signal levels used here they would be interchangeable but I didn’t suggest that.

 

Putting a splitter won’t damage your camera. Even if you were so incompetent that you inverted the signal and ground it wouldn’t hurt the camera. The voltage that powers the camera is supplied by the truck. I would put a 50 ohm terminating cap resistor on the unused terminal.

 

It wouldn’t be a good idea to ground the unused terminal.

 

I will order a camera.

    • I had an 88 K1500 with a 5.7 that had those symptoms, I know totally different, it ended up being the ECM. Once you get the fuel system fixed if it still runs lousy you may want to investigate that. it didn't set any codes, stalled ,ran rough at times etc
    • Congratulations Isttype, on your gmc. Really like my 2024 2500hd sle doublecab now with 85,500 miles.  I checked the oil today at 4800 miles since last oil change and barely reading on the stick.  I don't care if GM says it's Acceptable adding a quart every 2000 miles because that is 100% BS, It is not a 1966 Harley Shovelhead! Sounds like it's setting up a future failure like I had with my 1500 6.2l. Other than oil consumption problems, I really like the 6.6l gas and 10 speed is really nice.  Towed a light 4000 pound trailer last week and averaged 14 mpg.  I was pretty impressive that a 7300 pound gas truck did 14mpg towing, Later-
    • Long Term Cold Cycle Limited Testing   Back to the 1990's and XOM's million mile test. Since then there have been others and there will be more. Schaeffer's, AMSOIL to name two. Of these Schaeffer's is the stand alone which I will explain in a bit later.    http://papers.sae.org/600190/:   http://papers.sae.org/850215/:   Up to 75% of  engine wear occurs on cold starts. These two links (above) provide the technical reasons for engine wear. In a nut shell, and by a large margin, cylinder wear is what takes out most motors and even with a pre-oiling system that part of the engine is dry enough on cold starts and cold warm up to pierce Stribeck.   So when you put a motor, or a car, on a dyno for a million miles stopping only for oil changes, (yes fuel is uninterrupted) or break down maintenance, you are depriving the test of the most important part of it's wear cycle. Yes a million is then a pretty easy walk even for a mineral oil under those conditions.    How about cleanliness during the long test cycles? Same thing. Varnishes that stick rings and insulate parts are laid down by repetitive 'heat cycles'. It's the cool down the precipitates the varnishes. These long runs also hinder acidic attack caused by cold start richness and less than optimal cold start ring sealing. They hinder water formation and enhance breathing of the crankcase; the petri dish of acid formation, the first step in sludge formation, amalgamation and precipitation. These motors are also monitored and controlled for water and oil temperatures to within the "normal operating range".      https://www.swri.org/sites/default/files/sequence-iiih-test.pdf Note the test sequence in some boutique oils literature for testing, API IIIH, is not the standard used for the ILSAC G7 testing. Does that mean it is irrelevant? No, not as used. As used as a 'visual guide' it makes it's point. The G7 weighted piston deposit minimum is lower.      Back to Schaeffer's. That was a cyclical test of an engine in fleet service and not a dyno mule and if you saw the video it was not mirror clean but wear was low.    There are oils like BioSyn and other 'Renewable" source oils that taught cleanliness and have proven themselves in fleet testing. Havoline an other example.    The newest ILSAC G-7 test prioritize cleanliness, LSPI mitigation and fuel economy OVER WEAR. In comparison Porsche C30 Specification Verses ILSAC G-7 Specification below:      Some will balk that this graph isn't apples to apples and I will challenge that in that this graph represent the SPECIFICATION and not the any One Oil Performance.   It is absolutely possible to minimize wear, maximize cleanliness and mitigate LSPI etc., It just isn't cheap and currently I see none that are not walking toward profit over performance.     
    • I don't think you will need a split, separate product, etc., the OBD port should be able to deliver everything you need. Since your device would be plugged into it all the time, it wouldn't miss anything.    Hardware in this case will be the easiest part of your project - ELM 327 devices will already deliver all the data you need. Reporting/software is where your advantage/marketability is.
    • I do too. I’ll never be stuck again 😂
