My alarm is going off but only when the truck is running. If I hop in and touch the brake pedal it stops and it stops when I turn the headlights on.

any ideas?

Sounds like some kind of short in wiring. And it reminds me of when my horn honks if the vehicle is moving and the drivers door is open. And in the case if you apply the brake, the honking stops as well. Good luck. Wish I could be of more help!
