Radio delay for older trucks

[RustyBolts]

I started chasing this rabbit after I bought my V10. As well you may know from my signature, it's a 2000 model. I've also spent many hours behind the wheel of dad's '04 5.4L truck. His truck has radio and accessory delay, where once you turn off the engine, the radio, and windows still function for 10 minutes, or until you open the door. The first thing I noticed about my truck was that it had the window delay, but not radio. I started pondering how to do it on mine, and came up with a simplified solution for mine, that will work well on older trucks, if you want the radio delay.

If you need help deciphering the schematic, or have any other questions; please let me know. Hope this helps someone!

so you add two relays like you have in that schematic?

Yessir. You need to add one Normally Open, and one Normally Closed Relay or Two SPDT/5-post relays. They are not factory. Did I make it easy enough to interpret? I was worrying if it would make sense or not.

I understand it....
