The Rattler Do-It-Yourself system comes with a dual-relay pack
included for door lock operation. To interface this piece with the
system it is necessary to cut the three-pin plug off the relay
module leaving the three wires long enough to connect to the
system module.
Once you have cut the plug, strip a
3
/4-inch section of insulation
off the ends of the RED, GREEN, and BLUE wires. Solder the
LIGHT BLUE wire of the relay module to the LIGHT BLUE
wire of the eight-pin main haness, and solder the LIGHT
GREEN wire of the relay module to the LIGHT GREEN wire
of the eight-pin main harness.
Cover the two connections with electrical tape. The remaining
RED wire of the relay pack will be soldered to the RED wire of
the main eight-pin harness for a 12V supply. For additional
information regarding the wiring of the dual-relay module
contact Rattler Technical Support.

Engine monitoring
During remote start the system will need to know what the
engine is doing and how fast it is idling in order to determine if
the car is running. The module does this by monitoring the
voltage of the vehicle’s electrical system. When the vehicle is not
running the electrical system should read approximately 12 volts
and will increase up to 14.40 volts when running. The remote
start system monitors the increase to prevent the starter from
cranking when the vehicle is already running.
