1jz on honda v2 box (driftmotionPnP)

my car is going to get tuned this weekend so i was wiring in a relay for the fuel pump and e fans. i have the proper pins on the ecu pinned and connected but it wont power the fuel pump.  if i take the trigger wire off the ecu and put it to any power sorce it will run. does the ecu supply a voltage or a ground to trigger the relay?  same wiht the e fans? i have those wired the same but i am worried it wont run. i already went into the ecu and made the the pins are enabled. thanks!

The EMS itself has both

The EMS itself has both lowside and highside outputs. LS = ground, HS = +12v. You're using a third party adapter harness so we have no idea how it was wired or what outputs (LS or HS) are being used but if you check the pin out and see that a LS is being used, it means it has a ground output.

BTW this is the wrong forum section. Moving to Series 2 section.
