Our engine management systems have a versatile and broad feature set. This table help you choose which one is right for your project. Wire-In systems are more flexible, allowing you to create a custom harness from scratch, whereas the Plug-In ranges fit directly to the OEM harness, and bring the extra connectivity (not used bu the car in an OEM format) out through the AUX connector.
