How do I have my Reflex+ control my secondary pump(s)?

Connecting your Reflex+ to control our secondary fuel pumps is an easy and straightforward thing to do!   


  • Simply use the included "-trigger" harness which has two wires in it (green and brown), and route it from the fuel pump to the reflex.  
  • Then at the reflex you will utilize the included pressure switch and remove the switch itself and the brown wire from the connector.  
  • This should leave you with just the round 2-pin connector and a green wire.  
  • Simply connect this green wire to the AUX OUT that you wish to use (typically AUX2 - grey wire), and then connect it to the "-trigger" harness.  
  • From there your tuner will be able to control when the pump turns on!  


If using the standard relay, please ensure that the Reflex is set to 20hz duty cycle and has values of only 0 or 100 for the table, as any other values may cause permanent damage to the relay.
