How to disable VTSS module on jeep grand cherokee limited?

VTTS means vehicle theft security system.
If you remove the VTSS module, your security system will be disabled
It is located on right side of dash. This is the passenger side to the left of the glove box compartment.
The Vehicle Theft Alarm (VTA) module controls the operation of the VTA system. Power for the module is supplied from several sources. A constant battery feed is supplied on circuit X3. This circuit is HOT at all times, and protected by a 15 amp fuse located in cavity 6 of the fuse block. Power for the fuse is supplied by circuit A7 from the Power Distribution Center (PDC) fuse 14.
Power is also supplied by circuits F86 and F87. The F86 circuit is HOT in the ACCESSORY and RUN positions. This circuit is protected by a 10 amp circuit breaker located in cavity 27 of the fuse block. Power for the circuit breaker is supplied by circuit A31 from the ignition switch. Circuit F87 supplies power to the module in the START or RUN positions and is protected by a 15 amp fuse located in cavity 21 of the fuse block.
The VTA module uses the CCD bus to communicate with the Powertrain Control Module (PCM). Circuit D1 is the CCD (+) and circuit D2 is the CCD(-).
Ground for the VTA module is supplied on the Z1 circuit from two cavities of the module.
