anyone installed an aftermarket alarm system? i'm trying to get the oem factory alarm to work with the aftermarket alarm system and having trouble tieing it in. i was able to get the disarm to work. so i can disarm both system at the same time but cannot arm the factory system with the aftermarket transmitter. i am able to disarm the factory with the aftermarket transmitter. anyone had this problem? or any idea on how to arm and disarm with the aftermarket system. by the wat it's a solaris g-4 by clifford.
