Haltech E6K - Manual (Page 28)

Hall Effect and Optical triggers need three connections each - ground, power and the signal.
The trigger connector on the Main Harness has six 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). If your wiring harness is of the flying wire type
you should ensure that the trigger wire is shielded and that the shielding is properly grounded
to protect against external interference to the signal from “noise”.
PIN FUNCTION
A GROUND
B MAIN TRIGGER
C INPUT A (RELUCTOR)
D INPUT B (RELUCTOR)
E HOME
F 13.8 V DC
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 E6K 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 E6K.
Note: If you are using a motronic sensor read appendix E.2.2 Motronic Trigger
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.
