About 2 years ago I installed a BullDog remote starter. These can be purchased at Sam's Club for $50. It has worked very well. I was a little skeptical initially since it costs considerably less than other units with similar features. Most of the wires that it connects to can be found under the dash near the steering column. You also need to install 2 relays and tie into the door lock/unlock wires if you want to use that feature. I also wired mine to open the rear hatch and turn the interior lights on when the doors are unlocked. You will need 2 additional relays to make these features work.
