Mallory Ignition Mallory FIRESTORM CD MULTI COIL HARDWARE 69050S-69050R - Manual (Page 2)

MALLORY 2 www.malloryfirestorm.com
Connect the 12v switched ignition lead (labeled 12V SW) to a 12v
source that is live during crank and run. Consult your factory wiring
diagrams and verify with a test light. The Firestorm module must have
12v ignition power during cranking or the vehicle will not start. Connect
the VBAT lead directly to the battery positive terminal and the PWR
GND lead directly to the battery negative terminal. Connect the 10 way
coil out harness to the main coil harness.
The main coil harness is designed to connect to OEM GM Odd/Even
coil harnesses, or Mallory Even 77640 and Odd 77641 coil harnesses.
(The GM or Mallory SMART coil harnesses are a direct plug in)
Trigger Inputs
Connect the CAM/CRANK sensor adapter harness (LS1-LS6 78654M)
to 8 PIN Ignition (CAM/CRANK) Connector at the Module.
WIRE FUNCTIONS
Power Leads
Vbat - Red 14 ga - battery power- connect directly to clean battery
positive terminal
Power Ground - Black 14 ga - battery ground - connect directly to
clean battery negative terminal
12v Sw Ign - Red/white 12 volt switched ignition power - connect to a
12v ignition source that has power during start and cranking
Coil Connections
10 way multi coil out - Connect to the included main coil harness -
connect harness leads marked even and odd to their respective engine
coil harnesses.
Shield ground - Connect to a good, clean chassis ground to minimize
EMI noise. Due to the high energy output of the Firestorm module, it
is very important that shield ground wires are well grounded to ensure
proper operation.
Other Connections:
3 way MAP connector - connect to optional MAP sensor kit to expand
the tuning resolution of the Firestorm module based on engine load.
The Firestorm module defaults to an ignition curve that references
engine RPM only if a MAP sensor is not connected.

Accessory connectors:
There are 2 accessory connectors (8 and 10 pin) that can be used to
enable and control optional functions in the Firestorm ignition module.
Below is a listing of their individual functions and basic operating
description. Refer to the ACCESSORY HARNESS LAYOUT on page
5 or the software guide for information on configuring the Firestorm
software for proper operation of these functions.
Shift light - ground output to illuminate an external shift light. The
Firestorm module will ground this wire at the engine RPM you set in the
Mallory SparkMap software
MIL - Malfunction indicator light - ground output to illuminate a MIL
light when a trouble code has been set. The trouble code can be read
with the Mallory SparkMap software.
2 Step - a 12v input on this line activates the 2 step rev limiter based
on settings in the Mallory SparkMap software.
3 Step - a 12v input on this line activates the 3 step rev limiter based
on settings in the Mallory SparkMap software.
Signal Ground - provides ground circuit for sensor inputs such as ECT,
IAT and TPS.
VSS - Vehicle Speed Sensor input.
ECT - Engine Coolant Temperature signal input
IAT - Intake Air Temperature signal input
Fan 1 - ground output to control a single electric fan relay based on
temperature settings in the Mallory SparkMap software.
Fan 2 - ground output to control a secondary electric fan relay based
on temperature settings in the Mallory SparkMap software.
PTS - not used in multi coil applications
Tach - Engine speed output for an external tachometer or as an RPM
input to another module (i.e. Gen 7/Thruster ECM in fuel only mode)
TPS - Throttle Position Sensor signal input
UEGO - Universal Exhaust Gas Oxygen (wideband O2) sensor input
Data (0 to 5 Volt from Wide Band Module).
