*** IMPORTANT NOTE: Order processing can take up to 3 business days. Shipping timeframes start after the order processing has been completed. ***

Our engine harness is made with new high quality connectors, and automotive grade wiring. Carefully designed to run hidden in the engine bay to enhance the aesthetic "wire-tuck" look. The installation is less complex than our competitors, 95% plug n play. 

This harness is made with OBD1 (92-95) ECU Connectors. An ECU adapter can be used for OBD2 ECU's if needed however our harness does not support USDM OBD2 ECU's. Aftermarket ECU's using OBD2 plugs and NON-US OBD2 ECU's are compatible (except H22 and GSR stock units).

Each harness will come with a custom sub-harness depending on which chassis you order from our site. If you ever decide to change the chassis you would only require a new sub-harness. The engine harness will drop in to the new chassis without an issue.


***Note: Charge harness not included must be ran independently. Must run High Impedance injectors, is not compatible with a resistor box.
