Does anyone have a way to make a switch to not be able to start the truck? It would meed to disable the VP and the starter, because the truck can be bump started. It needs to be put on a switch in the cab, that way it is easy to operate for the owner, and not the thief. Stodg

Right from the fuel pump relay (Pin #87) in the PDC to the VP44 pump (Pin #7)

Your telling me this is the Fuel pump relay on the drivers side of the engine compartment in the fuse box right? and it just sends electricity to the Pump so i can cut and splice a relay into there and be fine yes?i would just like to be dam sure before i go about cutting wires in an engine compartment, don't want to make some mistake and cut the one that requires like 2v or something:banghead:

There is always the clutch interlock switch that prevents the starter from turning. On automatics the plug has a jumper that you can cut and put a hidden switch (SPST) under dash . The wire is right above the clutch location (or where it would be). The standard stick owner can just wire the switch in series that means clutch must be pushed to floor AND switch is "closed" in order to start. This also prevents starter and battery from getting overworked. My insurer gave me the $100 deductible back when an attempted theft resulted in broken windows only for me. Saved a lot of headache and cost me less than $4. on my 91.
