Matt* - Great Detail. I actually have the same bypass interface module but a different DEI system. Everything works but I have found one issue and curious if yours acts the same way.
If you arm the system while inside and manually unlock/open the driver door, neither the factory alarm nor the DEI alarm will go off. Probably because of the dome light delay as I get a Door trigger already registered upon arming system. So, then I arm the system from inside, wait 60 seconds (DEI door trigger clears). When I manually unlock/open the driver door, the DEI does not alarm, but the factory alarm does.
I can't find anything online. Any help would be greatly appreciated.
