What's useful that I've found on the physical IPDM cover is a diagram of what's what (steering, airbags, A/C, doors etc). Can't remember if it mentioned fuel pump.
Also not sure where to look for the wiring diagrams on the FSM. Is there a FSM just for wiring diagrams? This would help a lot in pinpointing the fuel pump relay circuit from the IPDM all the way to the fuel pump.
Main reason is I will be DIY'ing a killswitch for my Z off of the fuel pump relay circuit leading to the fuel pump.
Lots of old forum posts on this but all muddled up and links are expired on one of them that had all the wiring diagrams which ain't great.
Any helpful info will be much appreciated. Thanks fellow Z fam

Your best and easiest bet is to place this switch by the wiring of the pump.
A simple switch in the ground side of the pump will leave the power side of the wiring undisturbed. Placing the splice in the engine bay area is double the work + have to snake those wires inside of the car.
The pump wiring is inside the car already and routing the wires from the pump area to the center console or other areas will be a lot easier.
Good luck!
