You can look on this site maybe find what you're looking for they do have a switch option for multiple camera angles.    https://navtv.com/

To close this out. I didn’t have the wires backward . I had to put them back the way they were.   IT works absolutely flawlessly now, short of a voice command for the bumper camera, but when

do you have an io3 or io4 radio. the io3 is wired to the radio, the io4 the camera goes throught the hmi

I’m not sure, but I’ll have to look at that diagram some more. That might be very helpful. I am still determined/curious to figure it out just for the sake of figuring it out.

I just gave you the 2 easy plug and play options that everyone does. And have personally done myself.  

You must’ve posted while I was typing. I really like that third brake light camera absolutely won’t work for my situation, though. Mine is completely obscured by my cap on my bed..

I’m sure I can look around but $400 bucks for the GM mirror is just not real

 

I just ordered the “WOLFBOX G900 TriPro Bumper Version 3 Channel Rearview Mirror Cam”

I may get additional cameras had a switch..

I’m probably gonna use some of this really good Velcro I use on everything so I can move the camera from my bumper to the end of my we which sticks out like 3 feet in front of my truck when it’s.

in the rear, I’ll probably put wood in the license plate bracket on my liftgate and when I take the liftgate off, I may have one mounted on the bumper license plate or from the ladder rack.. I may or may not get some 10 foot extension cables so that way when I remove the items I listed above, I can just plug it in and avoid the switch altogether or at least for the front

You just use the camera from the 3rd brake light. You can mount it in the cap. I didn't search for the best deals on the stuff i just got you the part numbers.

Hey, I wired up the backup camera for my '12 to have a separate switch to turn it on, on-demand, as well as come on automatically in reverse, and for my '04, I can select an on-screen button on the radio to turn the camera on, but both radios are aftermarket.  Both radio's have a harness adapter with a small computer that listens to the computer bus on the truck, to find out when the truck is put into reverse (and some other stuff), and breaks that signal out into a separate "reverse" wire that connects to the radio.  For the oem radio, that happens inside the radio.

This other thread mentions a '14, where WAMS might be able to reprogram the radio HU to be able to turn the camera on/off:

You might be interested in that.

I gave him that option already.  I feel he wants cheap and hard way not expensive and factory functioning.

Dude, that's super frustrating with your GMC camera! It sounds like you've done a ton of work. Since you know which wires get power, the two black ones are probably for the video signal, like one is video positive and the other is video ground. You might need to find a wiring diagram for your specific camera to figure out which black wire is which for the video to show up. Good luck!

It’s not that. I just thought it would be easy.
 

The set up I bought which should be showing up tomorrow was $350 and I’m likely gonna buy an additional camera and a switch..

 

It’ll be great for backing up and added security of having a video of people stealing my stuff

I had removed my rearview mirror the other week. I wish I had done it 10 years ago, but in my state, you have to have it to get an inspection sticker even though it serves no function with the cap on. Just like the third brake light on the cab I got a rejection sticker one time usually they just change your lightbulb for you, but they wouldn’t do it because the cap was on there and they didn’t wanna struggle to change the bulbs, even though the brake light can’t be seen anywhere other than inside the driver compartment reflecting off the front of the cap.

 

by having the back up camera in my rearview mirror, I also wind up with a functioning rearview mirror.. it should be much more convenient. I typically just park where I pull forward that way I never have any issue, but sometimes you do have to back up which I’d use the mirrors but you’re still backing up blind even with the factory camera you can’t see anything anyway, especially if I have any of my accessories in my hitch. That’s why I’m probably gonna mouth the second camera high up on the ladder rack.

I already had run a spare wire when I ran the massive cables for my front/rear mount winch.. I just thought it would be as easy as tapping in to the always on blade for the cigarette lighter fuse with a switch and connecting it to a wire in the rear. It didn’t work out that way, even though it didn’t work out. I just have a spare power wire for anything else. I wanna run back there.

I got a J fuse holder just like the regular fuse holder in the photo so now I have access to constant power and accessory while ignition keyed.. I just have to pull that 50 amp J fuse, put it in the holder and then make a harness.

I don’t think I’m gonna install a fuse block.

it’ll just be the camera system, and the trigger power for my light bar controller, and battery isolator.

Not bad.. just need to finish hard wiring, connect GPS, program it.

 

I got Velcro on multiple places on the front. I can just move the camera around.

 

on the back, I’m undecided if I’m gonna install another camera probably

 

The rear camera has a red wire coming off of it that you hook up so when you put in reverse, it comes out automatically.

 

I just have to tie that to the white wire from the existing factory camera. Apparently, I learned that the hard way.

I ended up using the information from this thread
 

 

 

I used fuse 32 and 36 to tap off of. I think I had it backwards the first time because it was constant on. I just switched it and it seems to work fine. Other than that,The mirror says battery low one time and then another time it said battery level very low, but my truck doesn’t tell me any of that… I haven’t noticed it since I’ll have to check tomorrow

 

I swear, I thought I heard it making a noise when walking past it a little while ago while it was off, but I can’t be sure I didn’t have my hearing aids in.

 

I’m still using the accessory blade from where you would move the 50 amp cigarette lighter fuse if you wanted it to not constantly have constant power to charge your devices from for other stuff.

 

later today, I’m gonna be installing the smokers kit and swapping out that socket for a cigarette lighter installing the ashtray. I’m likely gonna hardwire in a quad lock mount/charger for my phone at some point…

I haven’t decided where I’m gonna get power from for that yet. Possibly a different location altogether. Currently drawing off the accessory for the cigarette lighter I have a three amp fuse that runs to both my battery isolator and my lightbar controller. I know I got a lot of extra wire, but I just always do that.


because I had repaired where I had cut the wires on the original back up camera, I peeled back the shrink wrap and bloom. One of those wires is literally just glued together from the factory, but yeah, I tapped into the white wire and all is good for reverse.

      Missing thrust bearing? And oil selection

      By Chuck FB · Posted

      Yes I agree, its what amounts to free advertising to let people know about his UOA testing company, and not that there is anything wrong with that but certainly that is a motivator for putting out videos about the science of oil as well as other topics such as oil and air filtration etc. The interesting part I found with his last video is not only the physics behind the reason for the varying wear due to a diesels working torque range causing more bearing load and that higher viscosity oil is of benefit, it was also that the chemistry behind the GM Dexos 0W-20 and the Mobil Dexos licensed 0W-20 are far enough apart that its showing up with a difference in wear even though the two oils are matched in viscosity and in that comparison viscosity was not having the finger pointed at it.    There are a few youtubers out there or one anyway that I have watched a bit of who has gone through the pains of accessing various countries manuals for a certain engine platform and while in the US/Canada it may say use 0W-20 or what have you for some Toyota product, in some other countries it sings a very different tune for the very same engine with the typical traditional oil viscosity/ambient temperature charts to help choose which oil viscosity is correct for the conditions the vehicle will be used in and in some cases its taken an engine in a US manual that states only use 0W-20 as per warranty coverage and yet that same engine in certain other countries may have up to a 15W-40 etc oil option that meets the spec. Another words the guy who is driving through Death Valley or Phoenix and south weather at 120f is often being fed a line of bs by the US system that has forced vehicle companies to restrict the warranty to a specific low viscosity oil for anterior reasons as well as the long drain interval suggestions.    Thankfully youtube is free ( yet anyway ) for viewers to sift through information and of course comes with the good and the bad ( truth and lies ) and we can choose to turn off/not watch what a person finds is bs or just not interested in the topic.

      No doubt... But, as someone who doesn't pay for his services, but who has provided a few views/clicks on his Youtube platform, the data around the Mobil oil testing I think does have some value including to "freeloaders" like me.   A lot of what he's doing is likely showing the OE's work in their oil selection, something that many of us had kind of assumed was true all along, a good balance of both excellent protection and efficiency.

      Lake Speed is drumming up business for his company just by being in the spot-light so he has a vested interest in stoking the 0W-20 fire.  IMO

      I knew when I bought my truck that it had off road hill decent or craw control or whatever they call it and rolled my eyes at that but it gets throw on with other options my truck has, I just never had a heads up if the highway speed regular cruise setting had anything to do with the brakes and that took me by surprise. If you've ever been to the top of Pikes Peak and watched those ahead of you on the way down with their brake lights on constantly, one can guess they are probably not gearing down or not enough anyway if their vehicle will allow and a good reason their is a brake check spot part way down where they use an infra red heat gun to check how hot ones brakes are front and rear.    Your right that once one gets out of the front range by Denver and I've not been on that stretch of 285 between Denver and Fairplay myself but I know its high and Fairplay at 10000 feet, Buena Vista at 8000, it drops a bit from there but then your going back up and over the 11000 pass and Durango is at 6500 . So yes your definitely right that 6500 and a lot higher is the theme of going anywhere out in that direction from Denver but hey, the down hill sections give fantastic fuel mileage !.    I don't even look at the fuel pumps for what premium costs here, since I live on a farm and up to this point get fuel delivered I am rarely in front of a fuel pump and when I am, I am often using card lock bulk fuel stations so it tells me what the price is AFTER I buy the fuel. Looking up on gas buddy and converting to US gallons but in Canadian dollars, regular on average of the prices listed was around 5.95 and premium is around 7.00 . That was one reason I did not go for the 6.2 half ton aside from its lack of carrying/towing if one was going by the rule of using premium fuel and until recently one could only buy regular farm gas if playing the few cents off game for farm dyed fuel for a "farm licensed pickup". But yes I hear you on the fuel price difference and like the diesel theme with it often being more expensive then gas it doesn't have quite the charm to it either as it once did although right now here for some reason the price of diesel has come down more so its now inline with the price of regular gas.

      I agree with this assessment. As you know I’m testing longevity with vehicles for the first time. I have a few vehicles I passed to kids and grandkids. We’re all past 100K miles some approaching 170K. I’m the only one doing 5k oil changes. The rest whatever the minder says. I’m the only one doing frequent transmission service. My odyssey the trip vehicle at 200K will be finished as a trip vehicle. I recently changed to high mileage oil, Valvoline. I can’t get past the fact that all manufacturers want to claim long service life. I just don’t make sense that they would go with low weight oil for mileage. While sacrificing longevity.
