Fuel Pump Relay Trigger?

I made the mistake of using the ignition switch stud for the relay which powers my accessory switch box and also has the fuel pump switch (goes cold when cranking!). Any suggestions on a circuit I can tap into that stays hot even when cranking?

Or should I just wire the fuel pump separately through a switch and the inertia switch…leaving the accessory switch box out of the equation?

I’m leaning towards pulling the switch out of the acc switch box and adding a separate circuit for the fuel pump on a switch. Just need to know where to tap into….

Not knowing this stuff specifically but thinking about how it "should" work you would need to grab the Run circuit and can tap something that is powered with the ignition system which has power during a start. The back of the ignition switch itself should have a Run terminal and whatever that powers will work, cannot talk you through the wiring and fusing other than the pump should be interposed with a relay from that circuit.
