How Plug’n’Play Adaptor Harnesses Work


If you’re looking for a quick and easy plug and play ECU solution and your car is not supported by the Haltech Pro Plugin range, then Plug’n’Play Adaptor Harnesses are your next best option.

Plug’n’Play Adaptor Harness allows you to use Haltech’s universal ECUs like Platinum Sport 1000/2000 or Elite 1500/2500 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 whole system.


The Plug’n’Play Adaptor Harness comes complete with an adaptor box which has factory harness socket on one side and three universal ECU inputs on the other.


The three connectors on your adaptor harness plug directly into the back of the adaptor box.


At the other end of the adaptor harness you will find two Haltech ECU connectors.


These plug directly into your Halech ECU, connecting it with the Plug’n’Play adaptor box.


With the ECU connected to the Plug’n’Play adaptor box the only thing left to do…


… is to plug your factory harness directly into the Plug’n’Play adaptor box.

With the ECU connected to your factory harness, you simply go online with your ECU 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.
