    I'm looking for a power source that is live only when the doors are locked. Is there something I can tap into? Don't need high current cause I can use a relay. I hope I explained it right. Thx.

    I want to add a horn/siren on the tonneau cover. If the tonneau is lifted, it will sound but not if the doors are unlocked.

    You could use the Tonneau cover trigger (I assume you're putting in some type of switch) to pulse the door switch of any door. It would mimic the door opening, thus triggering the factory alarm when locked, nothing when you're unlocked You need to relay and or diode isolate the two from back feeding each other. There's other ways but they require a status signal from the alarm to indicate lock/unlock. I don't know of one in our trucks, but haven't looked for one either. An aftermarket alarm usually has this type of status line out.
