Not sure what exactly is the secret. This can be pulled of other other subs along the same topic. And the owners manual Yall asked so...you're welcome?

The best method of preventing starting is to open up the PDC under the hood and look for the fuel pump relay there should be a black wire going to a ground bus. Unhook it and run it into the cab on a SPST toggle switch. The other leg goes to ground. So as long as the switch is on it will run normal. switch off the truck will not start and throw a P1689 code and set the CEL. As for the switch it has to hidden is such a way that neither the passenger or people outside can see you reaching for the switch to keep the secret. I though of mini switch behind my brake release since I'm a manual and I could release the brake and the toggle at the same time. Another spot under the left side of the seat that you maybe able to reach. Fuel Pump relay shown in the upper right corner. Just extend the ground lead in the truck add a toggle switch. Another way is to install a Quadzilla and set the program level to 1 and then set the fuel for valet mode to 10 or 15%. Now the truck may start but only moves about 15 MPH. You can use both as a deterrent. Here ya'll go enjoy!

Does anyone have a picture diagram explaining how to tap into the fuel pump relay wire and where? New to these wires and not sure what wire I'm looking for. I'm trying to install a kill switch on my 2001 2nd gen cummins.
