POWER MODULE INSTALLATION
The Power Module of the Atomic EFI system handles high
current circuits such as the fuel pump and WBO2. The unit has
two ports for the MSD CAN system as well as a wiring harness.
The CAN ports will provide communication between the Power
Module, the passenger side fuel/ECU rail and the Handheld
Monitor. It is important to select a proper mounting location for
the Power Module. The unit can be mounted in the interior or
the engine compartment as long as it is away from direct heat
sources. It is not recommended to mount the unit in an enclosed
area, such as the glove box. When
a suitable location is found, make sure all wires reach their
connections. Also be sure that the CAN port can be accessed
for use with the Handheld
Monitor. Use the Power Module
as a template and mark the
location of the holes. Use a size
#20 drill bit to prepare for the
supplied self tapping screws.
Assemble the sleeves in the
power module (Figure 16).

Not all of the wires from the
Power Module need to be
connected for proper operation
of the Atomic LS7 kit. Some of
the wires such as the nitrous
input, 2-step rev control, or
electric fan controls only need to
be connected if their functions
are being used. In the chart
labeled Power Module Wiring,
wires marked “REQ” must be
connected for the system to
operate while those marked
“OPT” are optional depending
on the features needed. For the
initial installation and start up,
it is recommended to connect
only the required wires.
Note: The Power Module
uses two heavy gauge wire
connections to the battery. Both
leads must be connected in
order for the Power Module and Atomic LS Truck kit to operate correctly.
• Connect the CAN from the fuel rails into the center CAN port on the Power Module.
• Connect the Handheld Monitor to the CAN port on the right side of the Power Module.
• Connect the 16-pin GT connector harness included in the kit.
• Connect the 4-pin Deutsch connect harness included in the kit.
• Connect the wideband O2 sensor included in the kit.
• Make all the necessary electrical connections.
