P/N 15838NOS
A5163-SNOS
INTRODUCTION:
This TIME DELAY BOX is designed to allow you to activate (time delay) or deactivate (turn off) a nitrous system based upon the
time constants selected on the box. Time range of time available is adjustable from 0 to 9.9 seconds in .1 second increments.
TYPICAL WIRING SCHEMATICS: INSTALLATION TIPS:
If using an NOS RPM switch (P/N 15879NOS), connect the yellow wire from the RPM switch to the green wire from the relay
that you desire to trigger.
Components used in this delay box are designed to handle a current load of up to 40 amps. If you intend to wire a system
without using relays, make sure the other electrical components you use are capable of handling the current loads of your
system.
If using a pushbutton to activate the delay box, connect it in place of the throttle (clutch) switch shown.
