I have a 2019 Chevy Silverado 2500hd Duramax LTZ Z71 truck. LOVE IT.
Problem 1:
The tailgate rear camera works fine. I can see it on the informant screen when I am in reverse. I have mounted an aftermarket camera for my camper. (Through Camera Source). This unit connects the camper camera to a relay as camera 2 and camera 1 as the tailgate camera. The other feed off the relay should be installed into the plug-n-play connector on the inside of the rear bumper (where the camera 1 was connected. This connection supplies the power for the relay and the rear camera. I put my truck in reverse and see a blue screen, no cameras are showing up. But if I run the camper camera 2 directley, it shows up. Camera Source replaced the relay, same problem. I am under my truck and see the rear bumper where the rear tailgate camera 1 plugs in. I have noticed that there are other (I guess plug-n-play connections) right beside this plug-n-play Camera 1 connection. What are these connections? Is there a wiring diaghram on this?
I have checked with my local Chevy dealer and even wrote to GM about this. They have suggested to get the Chilton Service manual for wiring diagrams. Yes, but nothing about the rear camera hookup or anything else. They all have said that on my 2019 truck, the last 4 or 6 numbers of my VIN # does not allow for their camera system.
Other aftermarket camera systems have a separate monitor with their systems. I want everything wired through the informant screen. I don't need front or mirror cameras.
Can someone help?
Problem 2:
I have purchased a dash camera and a laser radar detector. Both have the big 12v plug that you plug into the dash console. I would like to hard wire both units. To work when the truck is running. I have looked at my owner's manual and even looked at the fuse box diagram on the left and right and under the hood for what the fuses are. I am confused as to which fuse to pull and put a mini add-a-circuit holder in.
Any help.
Problem 3:
This truck has the old stile DEF filler tank under the hood. This unit does not have a gage to tell you how much DEF fluid is in the tank. Only a notice pops up on your screen saying that you have number of miles left on your DEF fluid and that your performance will be reduced. Is there a gage or something that can measure how much fluid is there. I even got a small dowl rod to stick in it for measurement.
So many questions, I did not want to post several questions.

For question 1 the other connections are for left tail light and right tail light.

Problem 3: when you get the message fill the tank.
The message will give you a mileage range several times as it counts down. IIRC first range is around 600.

Problem 2: there are a couple of fuses in right panel that can be repositioned to provide switched or full time power. Maybe Ron can give you the actual ones. You can piggyback off them.

Thanks for everyone who has answered my questions.
Happy Easter.

Your problem #2...I used F26 for the switched and F45 for always on, my dashcam turns on and off with the vehicle. You may need to buy a micro 3 fuse tap for F26 (I got one off of Amazon, pic below).
