I have an Infinity 6 with PnP Harness for my Evo 8.
I noticed that the PnP harness connect only PIN 22 for fuel pump and not connected the PIN 39 that is the pin for High Voltage.
Now...in this config I think that the fuel pump work only in low voltage condition and never in high voltage condition.
It's right ?
P.S.: total engine and electric harness is stock...and the low/high voltage circuit for fuel pump too! not rewired.
