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.

(1)

Wire

Black wires w/ring lugs

Orange flying Lead

Function

Coil ground wires that should be attached to the cylinder

heads.
A/C kick up wire. This should be wired to a source that

gets 12V then the A/C compressor clutch is engaged. This

will open the IAC up slightly and will also kick on fan #1

regardless of coolant temperature.
