if you select the hyper fuel command center you must use two separate 12 volt power supply to the each pump so from the control wire from the fitech ecu you MUST use two high amp relays (I use 60 amp) 1 primary 5 pin for your ecu control goes to that one the extra pin on the 5 pin relay will be the control to the second 4 pin high amp relay ( I use a 60 amp ) the other to the 1 of the pumps use 10 g grounds and use 10 g supply to each pump terminal and the hyper fuel ground needs to be within 12 inches and use a 10 g ground I contacted fitech about my all my connections was getting hot enough to start melting the sent two replacement pump thinking they may be pulling to many amps ,,technically they are if on the same single 30 amp relay I changed the pumps and no difference so I set both pumps up on there own power supply or circuit using the fitech fuel pump control to power up the relays and problem solved just a piece of info to share the hyper fuel is a really f n nice supply system well worth the money and it looks great under the hood
