Installation Considerations: This entire section should be read before starting the installation. An understanding of which control module wires to use
and their functions is essential. Installations will vary from car to car , as some control module wires are required, while others are optional. Before starting
the installation, it should be determined which control module wires will be used. Most installers will list these wires, then "map out" the installation by
locating and noting the target wires in the vehicle. This will also determine the best location for the EG-1800
ATV
control module, which is secured or mounted
only upon completion of the installation.
The EG-1800
ATV
duplicates, with onboard control circuitry and relays, the actions that occur within the ignition switch when the vehicle's key is used to
start the engine. Because of this, most of the main wiring harness connections will be made at the ignition switch harness. This will be located around the
steering column area. Caution! Avoid the Airbag circuit! Especially avoid any harness or wires encased in Yellow or Red tubing or sleeves. Do not use a
standard test light, as it can deploy an airbag or damage onboard computers and sensors if the wrong circuits are probed.
The ignition switch wires usually are high amperage circuits, which means that high reliability connections must be made! The recommended connection
method is proper soldering of all connections.

SUPPLEMENT
Make all the wiring connections and procedures in the following order. Remember, proper, high reliability connections must be made!
Chassis
Ground
Black Wire
Connect the Black wire to a very good, clean chassis ground. Recommended areas are to an existing machine thread bolt, either in the driver's kick panel
area or a major structural member behind the dash. Small dash braces are not adequate, and the area must be clean, bright metal. Use the largest existing
machine threaded bolt available. Using a sheet metal screw or grounding to sheet metal is inadequate. More comprehensive information regarding the
chassis ground connection is found on Pages 6-7.
Constant Power
Red Wire
Connect this wire to Positive battery voltage. The most common source is the battery's Positive terminal. If the battery is selected as the power source,
start at the battery and route the Red wire to the control module. Carefully route the long Red wire through the firewall, using an added or existing grommet.
Avoid any hot or moving parts. The fuse holder should always be close to the power source connection, not the control module. An insulated terminal is
provided for the control module end; this allows cutting the Red wire to length, if desired. Connect the ring terminal attached to the fuse holder to the battery's
Positive terminal. After all of the other wiring connections have been made, insert the Green 30 amp fuse into the fuse holder.
Some vehicles have a single Constant 12 Volt circuit supplying the ignition switch. A schematic of the car's electrical system will show if this is the case.
If so, the Red wire may be connected at the ignition switch wiring harness, but the fuse holder and 30 amp fuse must also be used.
The use of the 30 amp fuse and the fuse holder is required! Failure to properly install the fuse holder and the 30 amp fuse will void all warranties.
