The heXalink's® changeable interface allows you to connect to any OEM engine harness.  This means you no longer need a new breakout box for each type of engine harness simply swap the engine controller interface adapter (also called a "interface module") and the harnesses that mates with your new engine controller (see picture below) and you are ready to go!

Some of the off-the-shelf modules are shown below:
