Sideview Camera On When Changing Lanes? Possible with software update in 2019 trucks?

Buy one of these and plug it into the plug in your bed. Then hit accessory/no trailer when it asks. Then the camera will work with your blinkers till they figure out a way to program it hopefully. I've had mine in for about two weeks without a problem.

Someone on another thread had mentioned that this would disable some other features such as rear park assist, cross traffic alert and lane change alert though.  Curious minds wanna know

Sorry for the second post, I forgot to set "notify me of replies" after I last posted and it wouldn't let me edit................

I’m sure it does disable those features, as if an actual trailer was connected.

This should work even without a fake trailer. Normal everyday driving should have the most visibility around the truck as possible.

Yes it does disable those things when it's plugged in

I'm looking at doing this to test the "poor man's trailer camera" mod on this forum. Seems the truck will recognize a trailer if there is any <100ohm load on the trailer lights, right or left light pins but it doesn't like the load I have now and is throwing errors.

Just using some 10W chunky metal housing resistors.

Still trying to find what current won't throw an error on the DIC but my guess is it will be around >350mA per pin to think it has a genuine trailer connected.

Problem is 0.35A * 12V = 4.2W per line to dissipate in just heat is kind of crazy and will probably melt a plastic housing if not properly heatsinked  

Turn signals aren't a concern since they are seldom used, pulsed, and not on for long but the running lights and brake lights (left and right ON) pose the problem.

Not a problem for quick tests but probably not something you want to plug in just to override the software to allow use of the camera views while turning.

 

Will keep you all updated if I find a proper value and something that can work 24/7, either way you would have a 7pin connector stub always inserted...

Found that 75ohms or lower works to fool the truck into thinking you have a trailer with no light problems.

You can buy a 7pin connector end without the wires and 3 75ohm resistors to wire from ground to right, left, running lights.

Recommend 10W or higher metal resistors even 20W if they will fit (the more mass the better the heatsinking), I left them on for a while and they got up to 85C but still low enough to not melt the plastic connector housing.

If anyone wants me to make one for them let me know and I can make a listing on eBay for a tiny bit more than material cost + shipping.

Basically wired the three resistors, heatshrink wrapped them, tied with a zip tie internally and 3D printed a plug for the end. I made an ebay link if anyone wants to buy one.

Love the effort!

Perhaps one could install the trailer harness extension kit under the truck and connect the 7 pin connector to it for a cleaner look and no stub sticking out back of the truck.

I'm thinking to install one of these for other projects.
