REVIEW YOUR INSTALLATION
It is recommended to review your installation at this point. The 02 Sensor should be installed and connected
as well as the Power Module and corresponding wiring. Confirm that all of the rail wiring connections are
complete including the injectors and sensors. Ensure all fuel lines and fittings are tight and secure from
any heat sources or sharp edges. The next section will require powering the Atomic LS to go through
the Initial Setup menus and the fuel pump will run. DO NOT START THE ENGINE AT THIS TIME!
It is recommended to connect a Malfunction
Indicator Lamp (MIL) to your dash. A simple
bulb is required with switched 12 volts on
one side and this Light Green wire on the
ground side. If there is a malfunction in the
system, ground will be supplied through this
wire to illuminate the lamp.
