6 Ways to Wire In Your ECU
No.1 Direct Plug-in ECU
If you are after a simple plug-and-play engine management upgrade option and your car still has its original engine and wiring in it, a Platinum Series Pro Plug-in ECU provides the easiest and quickest solution.
Haltech’s Pro Plug-in ECU offer a host features not available on the factory ECU and are ideal for cars with low to moderate track useage. Simply unplug the factory ECU, and plug the Haltech Pro Plug-in directly into the factory harness. Load your base map and you’re ready to go!

No.2 Universal ECU + Plug’n’Play Adaptor Harness
If you want to step up to the Elite series ECUs and are still using the factory harness in your car, then Plug’n’Play Adaptors are your best option.
Plug’n’Play Adaptor Harness allows you to use Haltech’s universal Elite ECUs by connecting them directly to the factory harness in your car via a Plug’n’Play adaptor. This is an ideal solution for builders and tuners who want a quick and easy install without the need to rewire.
The Plug’n’Play Adaptor Harness comes complete with an adaptor box which has factory ECU connector on one side and the Haltech mating connectors on the other. The Adaptor Harness connects the Adaptor Box to an Elite ECU on one side and your car’s factory ECU harness on the other.
Once the Haltech ECU connected, you launch the Elite Software Programmer (ESP) and load your base map from the Haltech base map library. The base map will be sufficient to get your car going and give you a great starting point for further tuning.

No.3 Universal ECU + Plug and Pin
If your car is not supported by our Plug’n’Play options and you’re using the factory engine harness you can adapt the factory connectors to fit your Haltech ECU using a Plug and Pin method.
Simply remove the factory connectors and crimp the Haltech Plug and Pin set on. You can now connect your Haltech ECU directly to your factory harness.
