The only thing I can think you can do is use the HS fuel pump +12V signal and use the TPS setpoint to put 12V (arm the system essentially) and you must use a hobbs switch to trigger it with a boost setpoint. You MUST trigger the +12V relay with the HS pump output. It is not intended to power your pump direct.

Also, remember the HS pump MUST see a 25% below your on setpoint to turn the circuit off. Example, if you set it at 20% it WILL NOT SHUT OFF since it will never see -6% TPS voltage.

Hope this helps.
