Clifford and Viper

Clifford and Viper are both DEI, are they accessories compatable? like Clifford Smartwindows, Blackjax, Wireless Immobilizer, systems....

I would like to use some of Clifford accessories with a Viper 791XV

The older accessories are compatible, but some of the newer stuff (i.e. SmartWindows IV, Intellistart IV) will not be due to the lack of the Clifnet dataports on the non-clifford branded alarms.

is there a older version of the smart windows that will work? I like the vent feature.. how does the blackjack system work? is it compatible with the Viper? is there a way to add a responder remote to a Clifford G5 system?

Smart windows II will work if you reverse the siren's output polarity from (-) to (+). But you could also use a DEI 530T and get window venting. Blackjack works by cutting the ignition and starter systems after a set time when the last door is closed and the brake pedal is depressed. Every time a door opens, a code must be entered into a coded switch in order to deactivate blackjax. Responder remote will not work correctly on a G5.
