As always use at your own risk:
I would apply 12v to the fuel pump (plug unhooked) to the terminal that is fed by the gn/wt wire and ground the terminal fed by the br wire.
There are 2 relays involved:
fuel pump relay in position 13 on the relay panel in the left foot well.
the MFI/DI relay in position 1 on the relay board on the left side of the firewall in the rear trunk.
the pump is fed by a 25 amp fuse in c4.
