Your question is too broad for us to help.  Are you trying to firewall guests from the rest of the network?  Do you already have the ASA installed for your internal network and you need to add a guest network into it?  Where are the outside and inside interfaces (or DMZ) in the topology?  To many questions to give an answer....

Agreed, a planned use perhaps a topology diagram would help understand what you are trying to accomplish.

We have a asa firewall and we need to add a guest network to it we do not have any interfaces to use except the primary

Cheever000Commented:
So you used up all the physical interfaces?

In that case you can do 2 things one is consider subinterfaces, split a physical interface into 2 or more vlan interfaces this can be done it requires some additional configuration outside of the ASA

or use the out of band management interface as another routed interface, if you are not using this for management traffic it can be reconfigured for actual use.

To keep the guest network separate from the local network it will require an additional interface on the ASA, to add that if you have exhausted the total physical connections to the ASA you can migrate an interface to subinterfaces.  This does take some planning but just an example of this would be.  A lot pre-configuration needs to be completed to get this done, trunking the switch port on the other side, watching native Vlans on the switch ports, and of course if you remove an nameif in an asa it will rip all references from your config instantly, best way to complete this is to edit the config in a test editor back up the current running and copy the new config to the startup config, not the running, than reload upon reload the new config will take effect, and not rip out the references to the current nameif interface names.  Also the security levels you chose are up to you and your planed needs.

interface Ethernet0/1
 no nameif
 no security-level
 no ip address
!
interface Ethernet0/1.1
 vlan 1
 nameif inside
 security-level 100
 ip address x.x.x.x y.y.y.y
!
interface Ethernet0/1.2
 vlan 100
 nameif Wireless_Guest
 security-level 50
 ip address x.x.x.x y.y.y.y
