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 glovebox. 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. Install the supplied rubber grommets (Figure 14).
POWER MODULE
WIRING
There are a number of
electrical connections on
the Power Module that
are required for proper
operation (Figure 15). Other
wires, such as the nitrous
input, 2-step rev control or
electric fan controls, only
need to be connected if
their optional functions are
being used. In the chart
below, wires marked “REQ”
must be connected for the
system to operate while
those marked “OPT” are
optional depending on
the features being used.
For the installation it is
recommended to connect
only the required wires.
