Where are the alarm sensors for 2002 F150? Every so often the horn has a short beep and the interior, bed & parking lights flash when no key is in no one touching the truck? How do I stop this since the theft alarm can't be de-activated?

Asked by Smed39 Jul 28, 2015 at 03:09 PM about the 2002 Ford F-150 XLT 4WD SB

Question type: Maintenance & Repair

Horn sounds short beep, interior, bed and parking lights flash on then off, usually about
once and hour at night.  I pulled the horn relay so I can't tell if it happens during the day.  
Ford garage said it is connected to the theft alarm and one of several sensors is causing
it.  How can I trace this out and correct it since the alarm can't be de-activated?

Thanks for your answer. Are there any free shop manuals or wiring diagrams anywhere on line?
