This document is a wiring/installation diagram for the Commando EZ 2100 Remote Start & Keyless Entry System control module. It shows the module with its antenna and identifies all wire connections. On the left side, the high-current harness wires are labeled: Purple (starter wire), Orange (accessory), Yellow (ignition #1), Brown (ignition #2), and two Red wires for constant power. Top connections include lock (-) and unlock (-) outputs, a 3rd channel/factory disarm wire, an optional vacuum system connection, an LED, and a settings switch; one connector is marked 'Not Used.' The right side legend explains each colored wire: White to (+) parking lights, Red to +12VDC constant supply, Brown to a sensor's (-) trigger wire, Black to chassis ground, Orange to the 2nd channel (-) output (EZ-1100 only), Gray as a ground output when the engine is running (for VATS, anti-grind relay, etc.), Green wrapped around spark plug wires as a tach/spark sense wire, Blue to the included hood pin switch, Violet to the alarm's (-) trigger sensor input, and Yellow to the (+) brake light switch. A footnote lists dip switch settings (default ON) to turn off for tach/spark sense, vacuum switch, long crank, or diesel applications. Some connections are factory-set and should not be altered.
