Hey can someone help?

Problem 1- I installed a crimeguard 745i3. My problem is that when I arm the crimeguard the factory security  also activates.When I disarm the 745i3 the factory alarm goes off horn/headlights etc. How do I stop that?(I would appreciate very specific detailed info as I have no clue how to fix)
Problem #2-I cant get the dome lights to come on with disarming the 745i3.
