Pump is mounted below the tire well, under the car.

Secure wires with adhesive anchors and tie wraps.

Mount relay in the right rear corner of the spare tire well. Make sure wires are connected
as per the relay schematic below. Provide a good ground connection free of rust and
paint, for both the pump and relay. Connect the red power lead from the relay position
#30 to fuse #17 in the under dash fuse panel. Route the wire underneath the rear seat
and carpet. Take care to avoid sharp edges and not damage the wire insulation.
