POWER AND TACH SENSORS
INSTALLS
POWER CONNECTION:
FOR USE ON 6-400 VDC/VAC SYSTEMS ONLY!
Vapor will operate in the range of 6-400 VAC/VDC, but will not draw enough power to
drain a vehicle battery. Use a volt meter to confirm 6-400 VDC/VAC. Vapor is polarity
independent, so it cannot be installed backwards.
Fuse: Introducing a fuse into the circuit before electronics is always a good idea.
Use a 1 amp fuse with Vapor (not provided).
System Tap: It is possible to tap into the vehicle electrical system anywhere in the circuit.
Possible points are at the lights, ignition, or CDI. When tapping into the electrical system,
connect to a circuit protected by fuse.
MX Bikes: Most do, but some motocross bikes do not have 12 volt power. If there is no
vehicle battery or capacitor, connect power wire to ignition power leads from stator.
Use caution, as this is a high voltage option.

SENSORS:
Step 1:
Pull water-seal
down. Wrap
ignition sensor
around spark
plug.
Step 2:
Replace
water-seal.
Step 3:
Reinstall
spark plug
into motor.
OPTION 2:
If the coil is attached to the spark plug, then wrap the sensor like this:
Water
Seal

The ignition sensor enables tachometer readings and the
animated bar graph of Vapor.
OPTION 1: (Preferred option for most vehicles.)
Capacitive coupling to spark plug wire:
1.
If required, you may shorten the length of the ignition
sensor. Be very careful when stripping back the black
casing to avoid damaging the inner red wire.
To install ignition sensor wire, wrap the
red part of the sensor wire around the
coil wire 5 times.

The Vapor sensors plug securely into
Vapor using waterproof connectors.
They are different sizes (you cannot plug a
sensor into the wrong connector.)
