I'm going to hook up the aura opt 7 interior lighting on my limited, but im curious besides just hooking them to a fuse that turns it on when the car does, has anyone, or would it be possible to have them come on with the auto lights(Light Switch)? i wondered if taping into the hid fuse might work?

headlight fuse for ambient lighting?

It makes more sense to tap into whatever makes the instrument cluster and infotainment come on. If you have dimmable LEDs, you could go further and tap into the cluster dimming circuit. Then you can dim them with the stock dimming adjuster.
Im not fully familiar with that kit, so you’ll have to make sure amperages are OK and all that.

That’s a great idea I didn’t even think of that- so it’s a Bluetooth app you can dim and change colors etc. But I’d basically leave them on blue at one setting, that’s why I was trying to just have them come on with my headlights when in the auto setting for them?
Oh ok, I see what you’re saying you want. Give me a little bit, I’m going to see if I can remote into my software and see which fuse or relay you need to tap into. Since we pay for a limited number of slots for the software, if they are all being used right now then I will have to wait.
Edit: I need some info on your truck to be able to get the right diagrams.
I’d rather post it here so other people can reference it in the future. All I need is the year, model, trim package, and if it’s 4wd or not. (For inputting into the software). We can reserve the cell phone for when you really need it.
Good enough, the trim level is Limited. (I accidentally called it package)
This is a bit more involved than I thought it might be since you have to be careful with the canbus system. I don't feel comfortable giving you direction without studying the diagrams and maybe checking on my truck (which I don't have time to do for a while). I'm attaching info on the headlights circuit. I'm sure someone with more time available can study these and give you what you need if you can't figure it out.
This looks a little more complicated than say adding a fuse to fuse 26 on the headlight circuit. Seems my best option might be what I originally planned? If so do you recommend a fuse for adding on to so it just turns on with the ignition?
You have to give me a little bit (I think its fuse f66 or an adjacent one that’s ACC+), but you could do an add a fuse on the cigarette lighter circuit, or try what you were going to try. Look in the diagram for a headlight relay, that might be the safest bet if you go the headlight route
I looked into this, but you will need to do some testing yourself with a voltage meter. If you don't have one, I highly suggest getting one. It doesn't have to be anything special, and it will serve you well for your truck and house. Here's a couple: Klein DVOM Home Depot Fluke 101 DVOM Amazon
Because of the complexity of the adaptive front lighting system (AFLS in the attachments), I think the safest thing to do would be to use a dvom (NOT A TEST LIGHT) and check the white/violet wire coming from the sun sensor on the center dash speaker grille and see if it outputs 12v to the HVAC module then sends a signal over CanBus to tell the BCM to turn on the headlights. You can see that module on the left-hand side of the 7th page in the diagram I attached above, and the diagram is labeled "Fig.7 Headlights Circuit Premium". Again, use a multimeter for safety because I don't know what's being output by the sun sensor. Additionally, you will probably need to use some type of relay for your LED module, as the system will probably sense the sudden high current draw. (but maybe not)
Edit: If all of that seems like too much, check to see if the instrument cluster lights come on anytime the truck is on and the headlamp multifunction switch is in auto. If the cluster lights stay off until that happens, you could use that to power your interior lights. You will most likely need a relay depending on how your LED module is designed.
If that is still too much, do an add-a-fuse on fuse 33, with is switched power to the cigarette lighter.

thank you so much for that information, i was looking at fuse diagrams, and it looks like 66 or like you said 33 will work and they will just come on when i turn the truck on, the other stuff is a bit over my head currently ,but im hoping someone else can benefit from the wealth of knowledge you put on here, much appreciated
The F66 fuse is battery on all the time, so it sounds like you will want F33 so you don’t have to manually turn it off all the time. I don’t have a wiring diagram of your LEDs though, so I don’t know if it will need a constant and switched power, or just switched power.
it looks like the description for that says overhead console and heads up display, switch 911, switch assist, or maybe im looking at an incorrect chart?
i will just need a switched power, i wont need a constant
