Hello. I have a fedsig 650 handheld siren. I have one single viper s2 for aux 1 button. i'd like to set it up so when i push the #2 button I can have that single viper s2 on as well as a dual viper s2. However, when i turn on the aux 1 button, both viper s2's turns on. The single viper s2 power wire is connected to the aux 1 and #2 button wire. What can I do to "split" it so the aux 1 won't power the other dual viper s2 but yet turn on with the #2 button along with the dual viper s2? sorry for the noob question and hopefully it's not confusing. lol
