I don't think he wants to fix it right, Project. So, what SSCULLY was saying, Armored, is that the circuit is completed to ground to signal an open door. So, all you have to do is find the right wire and cut it. Since I don't have a wiring diagram for your truck, I can't tell you what wire that is. If you take the door panel off though, you can probably just disconnect the wiring harness to the door latch.
