Hello, I'm new to the forum and this is my first posting, I have just purchased (haven't picked it up yet) a 2004 F150 STX. It is in great shape and I have read the threads about the PATS system, the "Keys". My truck has non-powered windows and door locks, I was wondering about the security indicator light on the dash (in the left corner). What exactly is this telling me? Is there any type of "horn" sounding or "security system" on this truck, or is it just for when you insert the key?
Thanks
