System Wiring
6-Wire Starter Harness
Pin 1 RED - A: Main Power Input A (+). Connect to the battery or constant power wire at the ignition switch
with a minimum 30 Amp supply. Remove the fuse until the installation is complete and all wiring is
checked.
Pin 2 RED - B: Main Power Input B (+). Connect to the battery or constant power wire at the ignition switch
with a minimum 30 Amp supply. Note: if connecting at the ignition switch it is highly recommended
to use separate power wires for each Red wire, each with a minimum 30A supply. Remove the fuse
until the installation is completed and all wiring is checked.
Pin 3 BROWN: Second Ignition Output (+). The Brown wire provides +12V for a second ignition wire. This
wire may instead be programmed for use as a second accessory or second starter wire.
Pin 4 ORANGE: Accessory Output (+). Connect to the accessory wire coming from the ignition switch that
supplies power to the heater/air-conditioner. Some cars may have multiple accessory wires.
Pin 5 YELLOW: Ignition Output (+). Connect to the main ignition wire that provides +12V when the ignition
is on and while cranking the starter.
Pin 6 VIOLET: Starter Output (+). Connect to the the vehicle’s starter wire.
16-Pin Main Harness

Pin 2 BLACK/GRAY: Tach Input. Connect to the vehicle’s tach wire or a fuel injector wire if the tachless
mode does not provide satisfactory operation.
Pin 3 BROWN: Siren Output (+) 3A. The Brown wire must connect to the siren’s red wire. The Black siren
wire must be grounded.
Pin 4 GREEN: Negative Door Input (-), Connect to the door switch circuit wire that shows ground when the
door is open.
Pin 5 VIOLET: Positive Door Input (+), Connect to the door switch circuit wire that shows +12V when the
door is open. This type of door circuit is usually found on Ford vehicles.
Pin 6 YELLOW : Factory Rearm (-), this wire will pulse negative upon remote start shut down.
Pin 7 WHITE/BLACK: Hood Pin Input (-). Connect the to the hood pin switch. The switch must provide a
