You bet. Visit coastalflash.com and look at the rear camera in motion kit. It will allow you to view the camera for 25 seconds but you'll need a harness and some programming (part of the kit).

It’s way easier/ cheaper than that if you’re not looking to spend that kind of money on it.

If you go thru this thread, you’ll see where to connect a wire that will make your cargo light come on with your reverse lights. It shows where to put a diode connector to make that happen. But if you just use a wire instead of a diode in the same spot, whenever you press the cargo light button, the rear camera will turn on.

I purchased a dash mount wireless camera monitor and three cameras from Amazon for towing my TT.   It is a 7" monitor that allows me to toggle between the back of my trailer, the back of my truck, and the front bumper.  You can display up to four cameras separately or all together.  When I'm towing, I leave the trailer camera on and the monitor functions as a rear view mirror.  (You'd be surprised how many people hide in a trailer's blind spot!)  I sold the trailer and now just use the system's recording and viewing feature through my front camera. It is not discrete or OEM  in appearance but, at the time, the price was good and it does the job!

Use a wire instead of diode for cargo lamp/reverse with rear camera linked to cargo lamp switch.

There are a few reports that 2016+ trucks can’t turn on cargo light while in drive

Correct. Cargo lights won’t turn on but the camera does come on whilst driving. (In my 2018, but only when using a wire instead of a diode.)

Hey guys, my truck is a 2015 LT CCSB Texas Edition 2wd LT 5.3.

 

Cargo lights when in reverse, but the camera doesn't function with the cargo light switch.  Otherwise works as normal.  I double checked the pins in the picture, and I spliced the correct wires.

 

I also tried after putting in drive and above 30mph, just in case, same deal.

 

Any thoughts?

 

Thanks!

Well thats nifty. I didn't think that would work since the lights won't. But I might have to do that to my 18

So I did more looking at this and yeah it looks like the camera will only turn on with that button in park, and in neutral for me. Still handy for checking your trailer, tho not as nifty as I had originally assessed. Sorry for the late update I’ve been working away from home and didn’t have my truck with me.

Same situation on my 2018. Does not work in D or L. My cargo light and tow mirror side lights (throw light down side of truck) come in as well in R with the above mod.

      Cold start Miss, oil in cylinder

      By newdude · Posted

      Its coolant disguised as oil.   TSB 20-NA-166 -  20-NA-166 1..3   "To inspect for this concern, add coolant dye to the system, run the engine through warm up, pressurize the cooling system after warming the engine to operating temperature (let the engine cool overnight) and inspect the suspect cylinder with a borescope for coolant dye evidence. At times it may be necessary to remove the head for inspection. If the head casting line is the concern, the intake port will be wet with a coolant oil mix"

      Can you sample the pooled liquid, enough to confirm it is oil?   ...That its not fuel or coolant.   Also, make sure combustion gases aren't entering the cooling system.   Simply put, either oil being pushed up past the rings (this really isn't possible), oil leaking past the head gasket, oil leaking past the valve, oil entering through the intake air path. If none of this is likely - it may not be oil.   What could be likely is the fuel injector leaking down. A puddle of gas would still smoke and rough idle. (Same cylinder has the same problem after injector replacement?)   What is the crank time first thing in the morning, when the puddle would be present? Does it seem like the high pressure fuel pump needs an extra second or two to rebuild the pressure that injector 8 may have let bleed off? Check the fuel pressure via a scanner prior to starting the engine.

      Good information!  I didn't know about the dementia aspect and asked for a general for my second knee. I'd heard that recovery room time is usually shorter with a general.   The anesthesiologist talked me out of it and I had the spinal.  Inconvenience and/or discomfort is a small price to pay for reduced risk!

      This is for those over 70 years of age contemplating joint replacement surgery involving general anesthesia. Even some 55 yrs. ago when I took my pharmacology class the dangers of developing dementia in the elderly that had general anesthesia were beginning to be recognized. Over the years there has been some refinement in the cautionary warnings, avoid general anesthesia if possible if you've had close to 10 priors, especially over the age of 70 and/or a family history of dementia. I'm not including the twilight anesthesia induced by propofol often used in cytoscopies or colonscopies. Seriously think about seeing a neurologist and undergo cognitive testing before proceeding if any of those criteria apply to you. Spinal anesthesia may be an option in some cases. I'm in the above camp and although I could use a new right knee, I get fidgety according to a prior orthopedic surgeon when the bone saw spools up or maybe it was the smell of saw blade meeting bone, anyhow I may have one general anesthesia left in me which I will pocket for now and I'm choosing mind over mobility, anyway where did I leave my damn cane!
