A flex relay just means the relay can be switch on positively or negatively...... ie with patrols we switch positive to the spot light relay, 85 terminal is normally earthed and we switch power on and off via terminal 86.
You can also switch a relay on by suppling a constant power to terminal 86 and switch earth via an external switch to terminal 85.
Are there external relays mounted in the wire harness for the alarm system?
Do you have a wiring diagram for Viper?
Is your vehicle a manual? if so and you are planing on connecting the remote start you will need to mount some type of safety switch that prevents the vehicle from being started in gear.
