Flex Relay on a DEI Viper 4606 Remote Start

I am very confused about the extra onboard relay on my viper 4606 remote start . it states that if I need an accessory 2 then there is a flex relay that is onboard the remote start that must be wire up . there are 3 wires . can someone explain where the 3 wires hook up to ? it goes on a 2009 ford f250 king ranch . the accessory 2 wire is violet/green on ignition switch .

pink/black - (+) flex relay input #87a key side of flex relay
pink/white - (+)ignition 2 / flex relay output of flex relay #30
red/white - (+) fused 12v ignition 2 / flex relay #87

the pink/black (flex relay input)is #87a of onboard 2nd ignition/flex relay . this wire prevents having to use additional relays .
the pink/white ( ignition 2 /flex relay output ) typically connects to the ignition 2 circuit in vehicle . if doesn't have a ignition 2 but does have a accessory 2 or 2nd starter , it can be programmed to        be used power addition accessory or starter .
the red/white (12v input ) this wire connects to a 12v source and is the power feed for onboard ignition 2 / flex relay
