HA Motorsports custom ECU adapter harness for 92-95 Civic OBD1 automatic with B series engine and auto transmission swap. This harness will allow you to install one of our OBD1 auto ECU packages along with an OBD1 auto transmission control unit for use with an automatic transmission B series engine swap. This harness is made with all OEM connectors and pins for OE quality fitment and reliability.
The stock 92-95 civic with automatic transmission uses an ECU that controls both the engine and transmission. Unfortunately, the 92-95 Civic ECU cannot control a B series automatic transmission. By using this harness along with one of our OBD1 auto ECU packages, you can use the separate transmission control unit to control your automatic transmission to successfully tune your engine while retaining automatic transmission functions.
Notes:
- For use with an automatic B series engine and transmission swap. Will NOT work with the D series auto transmission.
- Works only with our OBD1 Auto ECU Packages and separate TCU, or the stock 94-95 Integra auto ECU part number 37820-P75-A51. Will not work with any other ECU or tuning setup.
- Must use either our OBD1 P78 auto transmission control unit or equivalent.
All HA Motorsports ECU's, products, and services include a One Full-Year VIP Warranty
