3.9 Fuel Booster Pump Electrical System Installation Procedures
Determine the location of the Fuel Booster Relay and Fuse Holder wire harness. Most common
installations locate these components inside the driver’s compartment and close to the fuse panel under
the dash. You can also mount the relay and fuse holder and harness close to the battery. However, these
connectors are water-resistant, not water proof, so care is required when mounting this assembly under
the hood of your vehicle

3.10 Fuel Booster Pump Relay and Fuse Holder Installation
The wire harness attached to the relay and fuse holder includes 8 feet of color-coded wires to make the
electrical system installation for you Edelbrock Nitrous System as easy as possible. We recommend that
you do not cut any lengths of wires from the wire harness or complete the wiring of the nitrous system until
all of the mechanical components are securely mounted in their permanent locations.
Use the wiring schematic on page 20 along with the Origin and Destination Map above to determine the
proper routing for the wires and their locations. Take caution as to not interfere with operating linkages,
heat sources, brackets, etc. Pay particular attention to sharp edges along the route of your wire harness
as they can chafe the wire and cause your system to fail.
Once all components have been securely mounted decide the location of the relay and fuse holder.
Secure them with fasteners (not included with kit) such as sheet metal screws, bolts and nuts, etc. Allow
for some slack in the red wire that connects the relay and fuse holder together.
When mounting your relay and fuse holder, make sure the mounting surface is strong enough to support
servicing the relay and fuse. Also, ensure you allow for some slack in the wire that joins the fuse holder
to the relay mount. This will avoid any potential loss of power due to stress on the wire harness. Be sure
to cover the fuse with the fuse mount housing.
