1.3.13. Install and connect any Optional Outputs
If you are planning to use any of the Programmable Optional Outputs, install and connect them
now. Depending on what options you are using, the wiring will be different. For details on
wiring your particular options, refer to Chapter 16, Auxiliary Outputs.
1.3.14 Connect the Trigger Sensor
If the engine has a magnetic trigger input, you will need to connect the Reluctor Adapter now.
For details on how to connect the Reluctor Adapter to the main loom and to the trigger, refer
to Appendix G, Wiring Diagrams, and to Appendix E [E.2].
Hall Effect and Optical triggers need three connections - ground, power and the signal. The
trigger connector on the Main Harness has four pins. These pins and their connections are
shown in the diagram below. The Secondary (Home) Trigger is used for Direct Fire or
Sequential Applications. (See Appendix B). The secondary input can also be used as the Road
Speed input if it is not being used as a home trigger.
You will need to know what wiring your trigger requires. Some triggers need a series resistor
on the power line in order to limit current. Check your trigger system thoroughly. An
incorrectly wired trigger can cause damage, usually to the trigger.
The E6A requires one trigger per ignition event. For example, a V8 engine will require 4
triggers per engine revolution. It is recommended the you read Appendix E, Trigger Interface
for more detailed information on the trigger requirements of the E6A.
1.3.15 Connect the ECU
The ECU can now be connected and tested. Be sure to engage the clip on the main connector.
This will make sure the main connector parts mate correctly and reduces the mechanical strain
on the connector bodies. The system can now be tested as described in the following chapters.
