  • Ensure all wiring is secure and properly fused.

  • Only use approved Flow Commander expansion packs.

  • Do not expose the unit to direct spray or submersion in water.

  • Mount in a location away from extreme heat sources.

 

3. What’s Included

  • 1 × Flow Commander Base Unit
  • 1 × Mounting Plate
  • 1 × Remote Control Fob
  • 1 × User Manual

Note: Mounting bolts are not included. Choose hardware suitable for your rig’s frame or panel.

 

4. Installation Instructions

Step 1: Mounting the Base Unit

  1. Choose a flat, secure location on your rig. Recommended areas: equipment panel, side frame, or control station.
  2. Use the included mounting plate to position the Flow Commander. Mounting bolts are not included.
  3. Ensure the unit is mounted upright and easily accessible.

Step 2: Connecting Power

  1. Locate a 12v power source on your rig.
  2. Connect the red positive (+) and black negative (–) wires from the Flow Commander to the power source. Most customers use the starter solenoid off the engine. The green wire will go to the black/white strip wire coming from the solenoid. The yellow wire will go to the yellow wire coming out of the engine block.
  3. Note: The Flow Commander already includes a built-in 12v inline fuse inside the unit. No external fuse installation is required.

Step 3: Connecting Control Outputs

For downstream applications, there is a Red/Black/Purple wire bundle that comes out of the control box. These will connect to the downstream injector bypass valve and will be controlled with button #4.
