Before attempting to wire your Edelbrock Performer nitrous oxide system examine and follow the wiring diagram on the following page Please call the Edelbrock Technical department with any questions concerning electrical wiring When working with electrical systems in your vehicle it is a good idea to have a service manual that features your vehicle It is also good practice to have a book that specializes the specialized techniques required when working with vehicular electrical systems 92003 Edelbrock Corporation Page 14 of 23 Rev 2 03 Brochure No 63 0148 8710 9 ON anyag 60 2 z 40 91 49010108P 20020 HOLIMSALJJYS lt 55 TYNINH3L SIHL OL LOANNOO LON OQ u3a1oHasnd HOLIMS labeo ote Add NS Gunn 5 221132913 SHOWIN Z 3 3 Nitrous Electrical System Installation Procedures Determine the location of the 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 harness 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 Wire Schematic Origin and Destination Map Wire C
3. Because Nitrous oxide is an oxidizer fuel selection is critical Both octane and fuel consistency affect fuel burn rate The oxidizer quality of nitrous oxide will accelerate the burn rate so we recommend a high quality of gasoline We also recommend you use the same grade of gasoline every time you use your nitrous oxide system This will help maintain the same fuel burn rate every time Ignition Components Most aftermarket performance chips increase the vehicle s ignition timing which can cause detonation with the use of nitrous oxide Please consult with your chip manufacturer on information regarding the compatibility of your chip with nitrous oxide use If your vehicle is equipped with platinum type spark plugs we highly recommend they be removed and replaced with the equivalent standard type spark plug Engine System Upgrades With all performance modifications complementary system upgrades will always serve to elevate the consistency and longevity of an engine especially when using nitrous oxide as a power adder Modifications such as ignition upgrades free flowing exhaust camshafts cylinder heads manifolds can all add to the performance of a nitrous oxide injected engine 92003 Edelbrock Corporation Page 6 of 23 Rev 2 03 Brochure No 63 0148 1 ea 1 ea 1 ea 2 ea 1 ea 1 ea 4 ea 1 ea 1 ea 1 ea 1 ea 1 ea 5 ea 1 ea 1 ea 1 ea 1 ea 1 ea 3 ft 2003 Edelbrock Corporation 1 4 Perfor
