The following installation instructions will outline the steps necessary to
connect your ECU with the provided Plug n Play harness.

WARNING!
It is recommended that the Haltech ECU be installed inside the
cabin to keep it away from heat and water intrusion. The front
cover must be installed to maintain IP67 water resistant rating.
If you wish to leave a USB cable plugged into the ECU then
you must contact your Haltech dealer to purchase caps for
each connector inside the lid as well as a sealed USB cable.
