Make radio stay on after key off

I have a '00 Lariat, and I am wondering if anyone knows if there is a way to make the radio stay on after the key is turned off, until the doors are opened? The windows stay operational like that, so I know there is circuitry somewhere for it, but where would I tap into that? I am thinking that I could just run the ACC wire for the radio that turns it on and off to that circuit, wherever that is...

Why? Just turn the radio off. Not like it'll kill your batteries.

Huh? Right now, it turns on when I turn the key on, and then off when I turn the key off, like normal. A lot of newer cars, the stereo will stay on after you turn the truck off, until you open a door, then it shuts it off, this is what I want to do. I have an aftermarket head unit, and it would be nice to be able to shut the truck off and continue to talk on my phone (thru the Bluetooth) without the stereo shutting off as soon as I shut the truck off.

Yes you can make it happen. I don't know what color the wire is, but you have to get the wiring harness for the radio and cut the right wire and plug it into a power source like you mentioned.

if you say the windows still go up and down when the truck is off but door isnt open yet, simply splice your radio power wire into the power wire for one of your door's window motors.

Do you have a circuit, in the fusebox, labeled "Delayed Accessory"? (look in the Owners Manual).

A bunch of electrical revisions were introduced during the '01 MY. Maybe that was one of them,,, that's the delayed accessory though, the delay is in turning the radio Off with a timer (or the door). If the 2000 doesn't have that circuit then I'm sure it's possible to build one and add it to the Radio supply line if you were into that kind of stuff

Perfect, that's the info I was looking for! I found a fuse diagram online (didn't get a manual with my truck) and I see that the relay #5 is marked as "Accessory Delay Relay". Is that what I am looking for? Sounds like it. Thinking I could just find which wire is hot coming off that relay (that also goes dead when the key is off and door opened) and tap into that for the trip wire for the stereo. Sounds simple enough, right? LOL
