THE RECEIVER/ANTENNA ASSEMBLY:
The Superheterodyne Receiver Antenna Assembly provided with this system allows routing from below the
dashboard for maximum operating range. Choose a location above the belt line (dashboard) of the vehicle for
best reception. Special considerations must be made for windshield glass as some newer vehicles utilize a
metallic shielded window glass that will inhibit or restrict RF reception. In these vehicles, route the antenna
toward a rear window location for best reception. Secure the antenna with double stick tape provided. After
securing the antenna with tape, we advise also securing a section of the antenna cable to a fixed support. This
will prevent the antenna from dropping down in case the double stick tape is exposed to extreme heat, which
may loosen its gummed surface. Route the 3 pin connector toward the control module using caution not to pinch
the cable as this will cause poor or no RF reception to the control module.
WIRING THE 6 PIN HARNESS:
RED w/ VIOLET
: +12 volts
Connect this wire to a +12 Volt constant source found at the vehicle's ignition switch using the 30 Amp fuse and
holder provided. This wire provides power for the control circuit as well as the ignition 1 and ignition 2 relays.
RED:
+12 Volts
Connect this wire to a +12 Volt constant source found at the vehicle's ignition switch using the 30 Amp fuse and
holder provided, but NOT the same vehicle wire as used by the Red/Violet wire above. Most vehicles have more
than one battery source supplying power to the ignition switch. Separate feed wires must be used for the Red
and Red/Violet wires. If your vehicle does not have two battery feed wires at the ignition switch then it is possible
to connect both wires to the vehicle's battery. This wire provides power for the start relay and the accessory relay.
IMPORTANT!
It is the responsibility of the installing technician to determine the load factor of the vehicles electrical circuits
when the vehicle is running and to adequately fuse the two power wires based on that load.
VIOLET:
Starter Output
This wire will have +12 volts when the ignition switch is turned to the start (crank) position only. This wire will
have 0 volts in all other ignition switch positions.
PINK:
Ignition 1 Output
Connect this wire to the ignition 1 wire from the ignition switch. This wire will show +12 volts when the ignition
key is turned to the to the ON, RUN and START positions, and will have 0 volts when the key is turned to the OFF
and ACCESSORY positions. For Diesel Applications, this wire must be connected to the ignition circuit that
powers the glow plugs if the vehicle requires glow plug pre-heating. (See selectable feature #8)
PINK w/ WHITE:
Ignition 2 Output
Connect this wire to the ignition 2 wire from the ignition switch. This wire will show + 12 volts when the ignition
key is turned to the ON or RUN position and is some cases the START position. This wire will show 0 volts when
the key is turned to the OFF and ACCESSORY positions.
NOTE: See programming information concerning this wire to function as a ACCESSORY wire.
