forcefully pulled or strained from the gauge itself. Route the sensor, relay
and pressure sensor cables avoiding contact with the exhaust system and
other vehicle components that could damage the cables. Also avoid routing
the cables near ignition components or other sources of RF (radio frequency)
and EMI (Electromagnetic interference) noise.
2.3 PowerSafe
Relay
The PowerSafe functions by intercepting the lead that controls the relay to
the nitrous solenoid(s). When the window switch function is used, the relay
will be open until engine RPM is within the programed range. Once in the
programmed RPM range, the unit will display “Armed” and the relay will be
closed. While the PSN-1 is “Armed,” nitrous cuts will occur if either the
Air/Fuel ratio and/or bottle pressure user defined thresholds are met.
1.
Disconnect the battery negative (ground) lead.
2.
Locate the trigger lead to the relay(s) originating from the arming
switch. Find a location that has enough wire length on both ends to
connect to the
PowerSafe
relay wires and cut the wire in half.
3.
Solder and heat shrink one exposed end of the trigger lead wire to
the
BLUE
relay wire. Solder and heat shrink the other exposed end
of the trigger wire to the
YELLOW
relay wire.
It is not critical which
side of the intercepted trigger wire connects to either of the blue or
yellow relay wires.
