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

/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 harness, 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.
