2.9 Electrical System Installation (WOT/Window Switch)
Refer to Figure 12 and the procedures in this section for electrical system installation.
WARNING! Death or injury may occur from working on a charged electrical system.
1. Disconnect the car battery at the ground cable (if not already done).
2. Install the WOT/Window Switch (27) as follows:
A. Find a suitable mounting location away from heat and vibration (ex. firewall).
B. Loosely route the WOT/Window Switch wires to the locations found on the drawing.
C. Route the Red / White wire from the WOT/Window Switch through the firewall. Route the wire as close to the center
console as possible
3. Install the NOS arming switch panel (leftmost switch) in the vehicle interior next to the power outlet, within easy reach of the
driver. See Figures 13-17. The NOS arming switch panel included in this kit has switches included for a bottle heater
(NOS P/N 14164NOS and 14169NOS), and an NOS purge (NOS P/N 16030NOS) which can be purchased separately.
Either the left most, or right most rocker switch can be used for a master arming switch. The middle pushbutton switch is
designed for a purge only. The arming switch is to be used to activate the nitrous system once safe engine RPM levels are
reached.
NOTE: Refer to the factory service manual for center console removal.
