You will need a data bypass module for the antitheft system and to control the locks and a few other features.
I would recommend a module from iDatalink or Fortin. They may need to be programmed for that vehicle, so make sure where you purchase them from can flash the firmware for that vehicle.
Make sure and test every wire connection with a multimeter to ensure a smooth install.
