You have not told us what kind of ASA and that could make some difference (in terms of how many interface it has available and its ability to support VLANs). Depending on some ASA variables you should be able to either configure a trunk port from the switch to the ASA and configure VLANs on the ASA to access the 2 VLANs on your switch. Or you might be able to connect an access port from VLAN 2 to one ASA interface and connect an access port from VLAN 3 to another ASA interface. Either of these alternatives should allow the management interface of the ASA to access both VLANs.
