Fed Sig Viper S2

[prty]

So I picked up a R/B viper S2 unit. Unfortunately I don't think this one is able to sync with other units considering there are only two cables RED and BLACK. However, I opened up the light and noticed the plug is a 4 pin plug. If I were to add some pins and cables into the plug would it be able to sync with other units?

Also, would I be able to swap sides with the color i.e. B/R instead of R/B?

So I spoke with fedsig support. The guy told me you could add two wires to it and it will sync, if its a 4 pin plug.
