Viper alarm goes off after 45 min

I know I read this somewhere in here, but I can’t seem to find it. I apologize if this has already been answered. I installed a Viper 791XV in my 2003 Ford F150 Harley-Davidson SuperCrew with Factory Keyless Entry. After the install, everything seems to be working fine. But after 45 minutes (Armed), the alarm goes off and my remote shows it to be the door switch. I checked it 3 times and all 3 were times around 45 minutes, give or take a minute or so. I wire the Green Wire (-) door trigger input from the alarm to the drivers door factory BLACK / YELLOW wire (-) and the rest of the doors to the BLACK/ lt blue wire (-) using diodes. I didn’t think I needed to wire anything to the factory keyless entry, so I didn’t. Please help?

The 03 f-150's pulse the door triggers every 30-45 min or so, to get around this problem just use the door trigger in the pass kick(BLACK/ blue if I remember right), and wire a relay in line to activate the door input on the alarm. The pulse from the bcm on the truck wouldn't be strong enough to trigger the relay, but when the door is open it will trigger it to sent a pulse to the alarm.
