The 457 will do the passlock bypass, but not door locks in that year truck. The Prestige pieces are very nice and very reliable. Just take your time, it's an easy truck, you should be fine. The light blue ground out while running is the wire you would connect to the bypass' status input.Installer, IT support, and FFL. I need less hobbies.

Twelvoltz is correct in regards to the light blue wire would be the remote start input wire.  When I first installed this system in a car I actually wrote down what wires are needed for the system to work(I'm a DEI guy).  For example if the door trigger is negative I would write it down and look in the manual for which wire that would be.  The difference I saw between this and a DEI alarm/remote start was the parking lights.  The white w/red trace wire needs a positve or negative feed.  If your vehicle had positive parking lights then connect that wire to 12v and connect the white wire of the alarm to the lights.  If it was negative connect the white w/red trace to ground and the white wire to the light.  Remember an alarm is only as good as the installer.

THANX GUYS THAT REALY HELPED A LOT WHEN I STARTED LEARNING (WELL STILL LEARNING) IS THAT ALL A REMOTE START IS JUST A COUPLE OF WIRES EXTRA.. LOL! THANX GUYS.. my friends call me butcher i fear no wires that dont belong.......................
