Car Alarms: Aftermarket Alarm Ford Explorer 1998 XLT, everthing works, alarmtek

Question
I have installed an aftermarket alarm system on a ford explorer 1998 XLT. Everthing works fine except that after about 45-50 minutes the aftermarket alarm goes off. This happens repeatly. This is the second aftermarket Alarm i have had installed and it has the same problem. Any Ideas???

Answer
Check the door trigger wires. Allot of people will
attatch both a negative and a positive trigger from
an alarm system. Yours is a positive trigger system.
Remove the neg door trigger from the wire it's on
if attached.

If that does not correct it, then tell me what
wire in the truck your alarm's door trigger wire
went to, so I can verify it's on the correct one.
