HA Motorsports custom ECU jumper harness for 96-98 OBD2A Honda Civic with an automatic transmission B series engine swap.
The stock 96-98 civic with an automatic transmission uses an ECU that controls both the engine and auto transmission all from the ECU. When installing an automatic B series engine swap into this chassis, you will encounter a problem with finding an ECU that will run the engine and transmission together as B series integra's use separate transmission control units. Using our custom harness, you will be able to use our tunable Neptune OBD1 auto ECU and OBD1 P78 transmission control unit in your civic and fully tune your engine while letting the P78 transmission control unit handle automatic transmission operation!
* Uses all OEM connectors and pins for OE quality fitment and reliability.
* MUST be used with our Neptune OBD1 auto ECU and OBD1 P78 Transmission control unit. Will not work with any other ECU or transmission control unit.
* We recommend using an OBD1 style B series transmission for this setup.
All HA Motorsports ECU's, products, and services include a One Full-Year VIP Warranty
