Hey guys.

First, this site is gold! What a plethora of information!

I have searched the database on here for the diargam for my truck but dont see the exact match. I need the alarm and remote start diargram for a 2003 Ford F-250 diesel, crew cab.

Also, I just bought the truck and I cant find any kind of factory lock module or keyless entry box, and there are no keyfobs with the truck. Where should I look? Are there any issues with installing an aftermarket alarm with or without a factory keyless box? Do I need a PATS module for the remote start? The car does not have the door keypads either.

Thanks in advance for your help!

Oh, forgot to mention, the truck is a XLT and has power door locks and windows.

PURRRRRRRRRRRRRRRRRRRRDY please! I looked in the database, but all the info there was for other cars-including the "2003 SuperDuty" which contained the wrong diagram (diagram there was for the F150 SuperCREW, not the Super Duty-F250 and up).
