ECUMASTER Adapter for the Nissan S13 SR20DET allows easier installation of the EMU Black standalone ECU to the J4/J5 ECU harness without spending hours making your own harness. All ECUs are sold separately.

Technical note on the S13 SR20 models:
Please confirm the ECU configuration by the label on the ECU. This adapter is designed for J4/J5/S15 64 pin ECU pinout configuration with exceptions of the ECCS and Fuel Pump relay (due to different regions of ECU configurations). This number designation can be found on the Nissan stock ECU label. Follow the Nissan 64 pin adapter link at the bottom of the page for instructions on your specific stock ECU model. 

We now stock an adapter for the 62/63-E5-QT-NQ ECU configuration in the following link.
