Type B: Negative-Triggered, Relay-Driven System - Viper 480XV Installation Manual

Type B: Negative-Triggered, Relay-Driven System

This system is common in many Toyotas, Nissans, Hondas and most European Ford vehicles.
The switch will have three wires on it, and one wire will test ground all the time. One wire will pulse
negative (-) when the switch locks the doors, and the other wire will pulse negative (-) when the
switch unlocks the doors. This type of system is difficult to mistake for any other type.
IMPORTANT! Remember that these wires' functions reverse between Type A and
Type B.
