After looking at options I have decided to go with the Toyota Fuel Pump Control PN # 89570-14240 which connects to ground, DI, FPC and the EFI M/REL circuit. It also doesn't need the Toyota COR or fuel pump relays, and still controls the pump speed.
So I picked up existing factory wires as shown in the attachments and threw the COR & fuel pump relays in a box.
I also looked at the Peel relay/switch CP-30 and made a wiring diagram for the off the shelf item along with a regular relay, see CP30 and relay to MX83 attachment. It also would use mostly existing factory wiring and get rid of the Toyota relays.
I couldn't work out how to include the fuel pump resistor circuit with the CP-30 setup though.
Cheers
