hello dear

the connection is simple we had two FTD nodes going to two Nexus switches each FTD box has two connection to N9K-1 and N9K-2 and for configration :

description To Firepower-vPC
switchport
switchport mode trunk
spanning-tree port type edge trunk
vpc 29

you need to allow VLAN in trunk that you allow it in vPC peer-link, 
this how vPC work.
