INJECTOR / IGNITION CONNECTIONS
Fuel Injectors
Label: Injectors 1-8 (EV1 plugs)
Label: Secondary Injectors (DTM-12 Black plug)
The Haltech LSx Non-DBW Terminated Engine
Harness allocates fuel injection into primary and
secondary stages
The eight primary injector output (1-8) connections
are terminated with Bosch EV1 plugs which
branches out into two groups for each of the engine
banks.
A secondary injector breakout plug (injector outputs
9-16) is also available and can be used with a
secondary injector sub-harness (sold separately).
See page 3 or visit the Haltech website for a range
of sub-harnesses to fit your application,
The last two injector outputs (17/18) are intended
to be spare outputs terminated with DTM-2 plugs,
but can also be used as tertiary injectors if the
application requires.

Crankshaft and Camshaft Position Sensors
(Label: Crank position, Cam position)
The crank position sensor plug connects directly to
the engine crank angle sensor.
The cam position plug connects directly to the
sensor, but note that the wiring varies between
models for the GM LSx engines. Hence the plug
has the signal wire (yellow) and sensor power wire
(red) both unplugged and is left for the installer to
"pin" into the connector to suit what the cam sensor
requires.
Refer to the table below for the pinout and insert
the pins into the connector until they lock.

Ignition Outputs
(Label: Ignition bank 1, Ignition bank 2)
This harness is designed to plug into the OEM
ignition sub-harness and therefore no ignition loom
is supplied. Ensure the correct ignition output is
connected to the corresponding coil bank on the
engine.
The harness also has two 13mm ignition coil ground
ring terminals that will need to be bolted on to each
of the engine heads to provide ground to the coils.
NOTE: If changing to a different type of ignition coil,
do not connect the ignition output wires directly
to the ignition coils unless the coils have internal
ignitors. In installations with ignition coils without
internal ignitors, an external ignitor must be used.
