General advice to answer your questions:

Follow the wiring diagrams. They're available in your Haynes manual, among other places.

The fuel pump wiring is in the main chassis wiring harness. The power wire runs to the 14-pin connector at the front of the relay board (pin 13, the left-front pin; black/red wire). The ground wire runs to the common ground point under the relay board.

The AAR power wire is in the engine wiring harness that connects to the 12-pin connector at the right-rear of the relay board. It is a white wire on pin 12, the right-rear pin. The connection into the fuel pump power circuit is made inside the relay board. The AAR is grounded through its case; there is no separate ground wire.
