PAC IGN-3 Latching Phantom Ignition Module 10 140 computer power adapter cord

PAC IGN-3 Ignition Module Purpose

The PAC IGN-3 Latching Phantom Ignition Module supplies switched accessory power in CANbus vehicles equipped with stop-start systems. It prevents aftermarket electronics from shutting down when the engine pauses at traffic lights. Installers working on modern vehicle electrical systems use this module to maintain consistent accessory operation. It detects engine running status to control the output wire automatically.

Simple Three-Wire Installation Steps

Installation requires only three wire connections for power, ground and the switched accessory output. The module latches onto the vehicle’s CANbus data to sense engine activity without complex tapping. A common error is reversing the power and ground leads which prevents the unit from powering up. Another frequent issue is selecting the wrong delay setting for the specific vehicle’s stop-start behaviour.

Selectable Delay Handles Stop-Start Cycles

The unit offers two power-off delay options: 10 seconds or 140 seconds. The shorter delay suits quick restarts in heavy traffic where the engine stops briefly. The longer delay covers extended stops at railway crossings or long traffic signals. If the vehicle’s stop period exceeds the chosen delay the accessory power will cut out until the engine restarts.
