Aeromotive 11109 - IN-LINE ELECTRIC FUEL PUMP - Manual (Page 10)

Section 3 - Electrical Installation:
3-1. Find a suitable place to mount the supplied relay, the relay is typically mounted by the OEM fuel pump wiring
connector (Never mount the relay inside of the fuel tank or next to fuel tank vents!). Insure the relay and any
associated parts are clear of the exhaust, any moving suspension or drivetrain components and any possible road
obstructions or debris.
3-2. Attach the OEM fuel pump wires (These typically are the red and black wires from the OEM wiring harness going to
the fuel tank) to relay terminals 85 and 86 using two of the supplied blue female blade connectors (See Figure 3-1
Below).
Note: Be sure to route all electrical wires clear of any moving suspension or drivetrain components, and any
exhaust components! Protect wires from abrasion and road obstructions or debris.
3-3. Find a suitable location for mounting the supplied circuit breaker. For optimal circuit protection, the circuit breaker
needs to be mounted as close to the battery as possible.
3-4. Connect terminal number 30 on the relay to the circuit breaker by using the supplied red 10 ga. wire, one of the yellow
female blade connectors on the relay end of the wire and one of the yellow #10 ring connectors on the circuit breaker
side of the wire.
Note: Be sure to route all electrical wires clear of any moving suspension or drivetrain components and any
exhaust components! Protect wires from abrasion and road obstructions or debris.
3-5. Connect terminal number 87 on the relay to the positive terminal on the fuel pump. This is accomplished by using the
supplied red 10 ga wire, one of the yellow female blade connectors on the relay side of the wire and one of the yellow
#10 ring connectors (or appropriate connector for the installation) on the fuel pump side of the wire.
3-6. Connect the negative terminal on the fuel pump to a clean chassis ground using the supplied black 10 ga wire and
two yellow #10 ring connectors.
3-7. Connect 12VDC to the circuit breaker using the supplied red wire and one of the yellow #10 ring connectors and the
supplied yellow 3/8” ring connector.
3-8. Ensure that electrical components and wires are connected properly (See Figure 3-1) and are clear of any moving
suspension or drivetrain components and any exhaust components! Protect wires from abrasion and road
obstructions or debris.
