I tried hard wiring my Sirius radio to my truck the same way I had it in my old jeep, my taking power directly from the head unit. Everything works like I wanted it to but the truck won't start because the security system is preventing the start. It's currently at my local ford dealer. Anyone have any idea I what they'll have to do to get it running like normal?

There is a relay in the junction box with a wire on it. That is the factory starter kill, get a standard Bosch relay, cut off pin 87, and replace it
