LUE wire from Nitrous harness Solenoid A Ground The purpose of the Fuel Pressure Safety Switch is to prevent the safety solenoid Second solenoid in line from opening and filling the manifold with nitrous without adequate fuel pressure This switch monitors the fuel pressure and only actuates over a pre set fuel pressure To test the wiring of your Performer Nitrous Solenoids make sure that the bottle valve is in the OFF position Turn the ignition key to the ACC position Use a jumper to connect the two terminals of the fuel pressure safety Switch therby bypassing the fuel pressure safety switch With the arming switch in the ON position quickly tap the microswitch button to activate the system You should hear the first solenoid click if wired correctly Make sure that you perform this test with the valve OFF to prevent filling the manifold with Nitrous Oxide Be sure to remove the jumper from the fuel pressure safety switch once done testing the wiring Catalog 71884 Rev 12 05 DC mc J ET MAP INFORMATION Edelbrock Engineering has conducted extensive dyno testing with the Edelbrock Dry Nitrous System on various vehicles to ensure the horsepower increase with the nitrous system is safe and functions as intended Ona typically stock 1 5L to 2 0L you can expect the following approximate horsepower gain Nitrous J etting Fueljetting Approx HP Gains 032 042 50hp NOTE This jet map i
