Sure. I did the same mod on my wife's wrangler. The button for that is in the top of the coin holder. You'd never find it if you didn't know it was there.

I ran a 12v from the drivers side fuse panel. See this post: I have a couple of wires running from the switch in the panel soldered to the back of the button on the remote PCB. I'll try and get some pics later.

I don't have pics behind the panel but there's plenty of space behind to mount it. It's mounted with Velcro to the back of the panel just so it doesn't rattle. It took me a couple of hours to install much of which was the fiddly part of soldering the wires to the remote PCB. I initially had the remote running off its own battery but decided to wire it to a switched source so someone can't just smash my window and get into my garage.

That works on my 2017. Press and hold the unlock button on the fob and all windows open. Unfortunately there is no way to close them all again other than manually. This has been discussed on here several times.

I couldn't bring myself to drop $200+ on a new console so I took an existing remote, bought a switch and a 12v-3v converter, wired the switch to the remote and the remote to RAP. The remote is tucked behind the console and secured with Velcro so it doesn't rattle around. Under $10 excluding the remote which I already had.

Well the truck knows when to warn you they're low so it must be programmed in there somewhere.

Not wise to remote start while it's in the garage. I tried to stop mine using the app while sat in it with the engine running. Wanted to see if it were possible if it were stolen but don't have the security feature through OnStar. The app threw an error saying "make sure the keys are not in the vehicle."

Tried this last night... Didn't work. I suspect this is a diesel-only option. I had the same thing on my motorhome with a Cummins diesel. Activated the same way. I used it when cold, primarily to air up the suspension and brakes faster. Another possibility is that it only works under certain (cold) conditions. If the engine temp is below 65 degrees. In Florida, I'm not gonna see those conditions for at least a couple of months.

Just push the OnStar button in the truck. When they answer, tell them you want to activate the 5-year basic plan. They will automatically give you 3 months of the full service and another 3 months for free if you give them your credit card. Just tell them you don't want the trial. The basic plan includes the remote app including remote start and remote lock/unlock. They changed earlier this year so if you bought your vehicle new after (I think) April 1st 2018, you only get 3 months free and then the remote app costs $15/month. Their top plan costs $60/month which is crazy. I would probably pay $10/mo for the protection and security package but no more.
