1JZ JZA70 SUPRA ENGINE TO 2JZ ECU PATCH CONVERSION HARNESS

This jumper harness is designed to allow you to use a 2JZ-GTE ECU on a harness for a 1JZ JZA70 (Supra) engine. It can be ordered one of two ways, with flying leads for the injector signal wires (to wire up for sequential injection, required for OEM ECUs) or plug and play for batch injection (which you can do if you are running an AEM or other aftermarket ECU).
