    Is there a way to provide power to my stereo while I am cranking the engine? For that matter, is it possible to delay during the stereo off after I turned the key? My old 2003 pickup gave me 2 min after turning the key off, and triggered of as soon as the driver door opened.

    Thoughts??

    You could wire up a relay like this one https://www.delcity.net/store/Time-Delay-Relays/p_804415.h_804416 to maintain power after the key is turned off.

    Keeping power on during cranking would require a different solution (but you might be able to use the same relay), since that design is built in to the ignition switch. Most vehicles cut off accessory power during cranking to provide more power to the starter.

    Here's a thought...Why? There's a reason it's the way it is.

    Because we can, of course! lol. I think that same question could be asked of most mods we make to our squares.

    For me, it is simply because of how I've grown accustom to using my stereo/phone. I am often driving and talking via bluetooth. When I arrive, my conversations are often not quite over. So, my current choice is to leave my truck running, waisting fuel, or shut if off and pick up the phone (1st world problems, I know!) I would like to choose option #3... turn off the truck and have a couple minutes to finish up my call =)

    I think i'm ruined, cause my '03 Silverado that I sold after I bought my '91 burb had this feature, and I used it all the time!

    My current radio stays powered on long enough for me to kill the engine and throw the key into the accessory position

    My Jeep has this option and i love it. I can turn off the car and finish listening to the song, and when I open the door the radio shuts off. I'd love to have this in my K5. Why? Bc it's cool. It's things such as this, i blame for my truck not being finished

    You can make it simple and untimed by using a relay to trigger the radio off when the door is opened.

    I've also heard of people wiring in a 4th gen f body RAP module. You would have to search for the wiring on that though. That would give you 10 minutes I believe.
