I believe that's correct, if you're referring to where the pressure switch return signal lands at on 2001 verses 2002(pin) stock ECU's. Unless I'm way off of what you're asking.Has anyone with a 2001 wired the oil pressure gauge setup to work?
I just want to confirm that it's pin E8 at the cluster side that needs cut.
2002+ wiring diagram posted shows E7
2001 wiring diagram shows E8
2001 is E6 pin 8(grey)
2002+ is E7 pin 7(grey)
Here is the complete 2001 schematic if needed.
