I am trying to put a kill switch to the fuel pump and i was wondering if ayone knew which wire to cut from the fuse box or going to the F pump. So that i can cut it and add switch. Thanks.
P.S.
My previous truck 04 Ram Quad Cab got stolen from my apartment parking spot, and used the insurance money to get an 02 Z06. So for sure i want a little extra peace at night with the kill switch. At least i will save money on gas compared to the Hemi, and be way faster too.

 

Why not put a kill switch in series with the clutch pedal switch? Either wire doesn't matter. Take your time and conceal your work as well as the location of the kill switch. I did this about 6 years ago. Works.

HTH,

I am thinking the fuel pump was a more effective, since it would require more work to be done in the engine conpartment or under the car, instead of under the dash. Also it will make some noise when it tries to start. But if i cant figure it out i will add a switch to the clutch for sure.

Does anyone have a diagram for the wiring going to the fuel pump?

 

Just find the fuse or relay that goes to the fuel pump and wire it in there. The secret is to hide your switch really well.

 

Thief is most likely going to figure fuel cut-off switch anyway, but regardless it will slow down a bad guy looking for the switch or bypassing it.

All you can hope for is to slow someone down anyway. It can be put on a flatbed in a couple minutes, then in an enclosed trailer around the corner, then to South America.

 

The car already has a fuel cutoff mode. If the proper key is not used the antitheft system inhibits the fuel and starter for a period of 3 minutes. Here is how it works:

The PASS-Key® system prevents the engine from starting by controlling the theft deterrent relay and the powertrain control module (PCM) fuel enable input. If the PCM does not sense the proper fuel enable signal, fuel will not be provided to the engine.

If the wrong resistance value is sensed when the ignition switch is in the RUN position, the BCM will not ground the theft deterrent relay control circuit and will not provide the fuel enable signal for approximately three minutes. The engine is prevented from starting and discourages a thief from trying key codes or resistance values at random.

If the correct resistance value is sensed when the ignition switch is in the RUN position, the BCM will ground the theft deterrent relay control circuit and enable fuel delivery. The engine will start normally.

If the PASS-Key® system detects an open or short to ground when the ignition switch is in the RUN position, the BCM will default to fail enable mode. Fail enable occurs when the proper key resistance is sensed before the open short to ground occurs. Fail enable will illuminate the security indicator lamp and allow the operator to stop and start the vehicle until the problem is corrected. The PASS-Key® system includes the following components:

Ignition key
Ignition cylinder
Body control module (BCM)
Theft deterrent relay
Powertrain control module (PCM)
SECURITY indicator
Ignition Key
The ignition key is a typical square ignition key blank with an imbedded resistor. The key blank and resistor are not serviceable separately. There are 15 different resistance values. The ignition key also has mechanical cuts similar to non-PASS-Key® ignition keys.

Ignition Cylinder
The ignition cylinder contains a set of electrical contacts used to measure the resistor in the ignition key. When the ignition key is inserted into the lock cylinder, the resistor in the key makes contact with the electrical contacts inside the ignition cylinder.

Body Control Module
The Body Control Module (BCM) contains the theft deterrent system logic. The BCM reads the key code from the ignition cylinder when the ignition is turned to the START position. If the code is correct, the BCM will enable the theft deterrent relay and will send a fuel enable signal to the PCM via the class 2 serial data circuit.

If the BCM receives the wrong code, the BCM will immediately go into tamper mode. The tamper mode will lock-out the vehicle starter and fuel injectors for 3 minutes. The SECURITY indicator will flash while the BCM is in tamper mode.

Theft Deterrent Relay
The theft deterrent relay is used to prevent the engine from cranking if the correct resistance is not sensed at the ignition key. It prevents the engine from cranking by opening the circuit to the starter solenoid.

Powertrain Control Module
The PCM communicates with the BCM over the Class 2 serial data circuit. When the BCM enters tamper mode, it sends a Class 2 message to the PCM in order to disable the fuel injection system. If the BCM receives the expected ignition code, the BCM sends a class 2 message to the PCM in order to enable the fuel injection system. The PCM then allows the vehicle to start.

here's a few pics, the wire that goes to the pump is grey/white, i forget the pin, but ck the pics it should be there
http://www.lingenfelter.com/document...pSchematic.doc
it's the harness w/ the light green tape(you'll see all the different colors next the batt., yes, it is possible to connect some of the conn. together incorrectly if not be aware of the tape color)

 

The beauty of kill switches is that even with the correct key, the car still will not start. Not to mention the fact that a kill switch is really cheap too. Short of a wrecker, it aint going nowhere.

 

Thanks I will use that one to interupt the power to the fuel pump.

 

Connecticut props on the info, switch worked like a charm. The only way they are taking the car is with a tow truck.
Better safe than sorry. If anyone has questions thow me a PM.

 

If you think by keeping your Z06 outside in an apartment parking spot it will be protected by a fuel pump kill switch, think again. If they can see the car and want it, it will be taken. Your best bet is to park the car inside a garage, out of sight. So get out of an apartment and into a house.
