I called Haltech support last week and was told to use one of my AUX outputs to close the relay for my 2nd Bosch 044.
There is one main pump running all the time and the second pump will come on based on boost pressure (over 18psi)
My question is how to wire the relay coil with the AUX output1? Is AUX output1 a 12V output from the ECU and go to the relay coil (85)? And 86 go to ground? Because I have read on other threads that 85 should be wired to a switched 12V supply and 86 back to AUX output1?
