Fuel Pump Relay is inside the IPDM.
ECM terminal 22 to IPDM terminal 77. This wire activates the fuel pump relay in the IPDM when the ECM commands it.
IPDM wire 13 to fuel pump module terminal 1 is the fuel pump power wire.
There are wiring diagrams towards the end of each FSM section that needs them. Towards the end of the ECS section is where you will find all the engine control wiring which includes this information. The PCS section has a more detailed IPDM diagram (more like halfway through the PDF) but doesn't include the ECM end of it.
You might find it easier to tap in at the ECM end since its already inside the cabin, if thats where you want your switch.
