I installed a 791xv into a Fusion a couple of days ago,but the alarm keeps going off showing the trunk is opening..it will do it only after sitting for a couple of hours though. I wired the car according to directech, including the factory alarm disarm wire... i think this may be the problem, just looking for feedback.

Most new fords have a self check system which sends a short neg pulse out after the car has been idle for around 2 hours. The only way to get round it is to use a relay to feed the alarm.

30 - ground
85 - 12v +
86 - boot light switch
87 - alarm boot sensor wire.

Thankfully the pulse doesn't have enough juice to trip the relay.
