Ignition #1 Ignition #2
The AviStart module has two onboard 30-amp relays. Most vehicles have only
one ignition wire necessary to start the vehicle. Some vehicles have two
ignition wires. Make all wire connections at the ignition switch wire harness.
1 . Use a voltmeter to locate the wire(s) that show +12 volts while the ignition
key is in the "ON," "CRANK" and "RUN" positions and 0 volts when the
ignition key is in the "OFF" position.
2 . Connect the 14 ga
PINK
wires to the vehicle ignition wire.
3. If the vehicle has a second ignition wire, connect the other 14 ga
PINK
wire.
Heater/AC
The AviStart module has one onboard 30-amp relay. Most vehicles have only
one heater/AC wire. If additional heater/AC wires are required to activate the
vehicle’s heater/AC system, an additional 30-amp relay must be added. Do
not use the
GRAY
wire to power more than one heater/AC wire.
1. Use a voltmeter to find the wire(s) that show +12 volts when the ignition
key is in the "ON" position, 0 volts while the starter is cranking and +12
volts while running.
2 . Cut this wire in half. Start the vehicle and turn the blower switch on. The
blower should not turn on.
3. Connect the
GRAY
wire to the heater/AC wire.

WARNING
: Review the "Safety Bulletin" and diagrams on pages
9-11 prior to installing the starter system.
1. Use a voltmeter to find the wire that shows +12 volts while the ignition
key is in the "CRANK" position
only
and 0 volts while the key is in the
"OFF," "ON" and "RUN" positions.
2. Connect the
VIOLET
wire to the starter wire.
Glow Plug Light Input
The AviStart can start a diesel engine by one of two methods.
Pre-ignition
The module can be programmed to turn the ignition "ON" for 15 seconds
before the starter engages. This will allow the glow plugs time to warm up and
the glow plug light to turn off.
