WIRING THE 8 PIN MAIN POWER HARNESS:   

PART # 1124299

NOTE:

Do not remove the fuse holders from this wire harness.  Fuses must be 

used and located as close as possible to the power source for adequate protec-

tion of the vehicle.

 1 BLUE Wire: 

 Ignition 1 Output

Connect this wire to the ignition 1 wire from the ignition switch.  This wire will show +12 volts when the 

ignition key is turned to the "ON" or "RUN" and the "START" or CRANK" positions, and will have 0 volts 

when the key is turned to the "OFF" and "ACCESSORY" positions. 

For Diesel Applications, this wire must be connected to the ignition circuit that powers the glow plugs if 

the vehicle requires glow plug pre-heating. (See selectable feature Bank 3 #12)

 2 RED/WHITE WIRE:

  + 12 volt Battery 1 Source Fused 30A

Locate the vehicle battery wire(s) at the ignition switch.  Verification: These wires will register voltage in all positions 

of the ignition switch.  Connect the Red w/White wire to the vehicle's battery wire.  This wire provides power for the 

control circuit as well as the ignition 1 and ignition 2 relays.

 3 GREEN Wire:  

Ignition 2 Output

Connect this wire to the ignition 2 wire from the ignition switch.  This wire will show + 12 volts when the 

ignition key is turned to the "ON" or "RUN" position and is some cases the "START" or CRANK" position.  

This wire will show  0 volts when the key is turned to the "OFF" and "ACCESSORY" positions.

NOTE: See programming information (Bank 3 Selection #7) concerning this wire to allow output during 

the "START" mode. 

 4 PINK Wire:

 Additional Ignition Output

This wire can be used as an addi 12 Volt ignition output supplied by the Red/Black wire.  This 

output can be selected to be on or off during the start cycle.  (See feature bank 3 selection # 8)  Connect 

this wire to the third ignition circuit in the vehicle and set the selectable feature # 8 of Bank 3 according 

to the way in which the vehicle's ignition switch operates. 

 5 PURPLE Wire:

 Accessory Output

Connect this wire to the Accessory wire from the ignition switch. This wire will show + 12 volts when the

ignition switch is turned to the "ACCESSORY" or "ON" and "RUN" positions, and will show 0 volts when

the key is turned to the "OFF" and "START" or "CRANK" positions.

 6 RED WIRE: 

 + 12 Volt Battery 2 Source Fused 30A

Locate the vehicle battery wire(s) at the ignition switch.  Verification: These wires will register voltage in all positions 

of the ignition switch.  Connect the Red  wire to the vehicle's battery wire.  This wire provides power for the start 

relay and the accessory relay.

YELLOW Wire: 

 Starter Output

Careful consideration for the connection of this wire must be made to prevent the vehicle from 

starting while in gear.  Understanding the difference between a mechanical and an electrical
