AUXILIARY CONNECTOR
Auxiliary Connector
The 16-pin auxiliary connector located on the rear side of the adapter provides additional inputs and outputs
that link to the Nexus ECU. The kit is supplied with spare pins that you can use if you need to connect to
these additional I/Os. Use an appropriate crimping tool, such as the HT-070300.
Please refer to the pinout information below for details on the spare inputs and outputs available for this
application.

Unless specified otherwise, Haltech warrants its products
to be free from defects in material or workmanship for a
period of 12 months from the date of purchase.
If the Haltech product is found to be defective as men-
tioned above, it will be replaced or repaired if returned
prepaid along with proof of purchase. Proof of purchase
in the form of a copy of the original purchase invoice,
receipt or bill of sale which indicates that the product is

Replacement or repair of a defective product shall con-
stitute the sole liability of Haltech. To the extent permitted
by law, the foregoing is exclusive and in lieu of all other
warranties or representations, either expressed or im-
plied, including any implied warranty of merchantability

or consequential damages.

Please include a copy of the original purchase invoice,
receipt or bill of sale along with the unused, undamaged

with missing accessory items or packaging will incur ex-
tra charges to return the item to a re-saleable condition.
All product returns must be sent via a freight method
with adequate tracking, insurance and proof of delivery
services. Haltech will not be held responsible for product
returns lost during transit.
Returns of Products Supplied in Sealed

Installation of Haltech Products
No responsibility whatsoever is accepted by Haltech for
the fitment of Haltech Products. The onus is clearly on
the installer to ensure that both their knowledge and the
parts selected are correct for that particular application.
Any damage to parts or consequential damage or costs
resulting from the incorrect installation of Haltech prod-
ucts are totally the responsibility of the installer.
Always disconnect the battery when doing electrical
work on your vehicle. Avoid sparks, open flames or use
of electrical devices near flammable substances. Do not
run the engine with a battery charger connected as this
could damage the ECU and other electrical equipment.
Do not overcharge the battery or reverse the polarity of
the battery or any charging unit. Disconnect the Haltech
ECU from the electrical system whenever doing any
welding on the vehicle by unplugging the wiring harness
connector from the ECU.
After completing the ECU installation, make sure there is
no wiring left un-insulated. Uninsulated wiring can cause
sparks, short circuits and in some cases fire. Before at-
tempting to run the engine ensure there are no leaks in
the fuel system.
All fuel system components and wiring should be mount-
ed away from heat sources, shielded if necessary and
well ventilated. Always ensure that you follow work-
shop safety procedures. If you're working underneath a
jacked-up car, always use safety stands!
