Arnaud, you don't need the ground signal from the dash switch to pin 85 for your setup unless you want to manually switch on the pump. Either remove the current wire to pin 85 (disables the dash switch) or connect your EZ fuel pump wire also (enables both ecu control and manual override).

Hey, if you disconnect the dash switch, you could always use it to control a seat heater to keep your buns warm during those brisk Chicago drives!
