3.2 Wide Open Throttle Module Wiring Diagram
3.3 Nitrous Electrical System Installation Procedure
Determine a location for the wIde open throttle relay and fuse holder wire. Most common installations locate these components
close to the battery. However, these connectors are water resistant, not waterproof, so care is required when mounting this
assembly under the hood of your vehicle.

3.4 Wide Open Throttle (WOT) Module Installation
The WOT module includes 3 feet of color-coded wires and terminals to make the electrical system installation for your 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 system until all of the mechanical components are securely mounted in their permanent locations.
Once all the solenoids and switches are placed, route the un-cut wires from the harness to each location allowing enough wire
length on each circuit 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 you have decided the location of the “WOT” module secure it with fasteners (not included with kit) such as sheet metal
screws, bolts & nuts, etc. Allow for some slack in the red wire that connects the “WOT” moduel and fuse holders together.
