HA Motorsports custom ECU harness for OBD2B 99-00 Honda Civic with an automatic transmission B series engine swap. This harness allows you to use one of our OBD1 AUTO ECU packages with a separate transmission control unit. The stock 1999-2000 Honda civic with automatic transmission controls both the engine and the auto transmission from the same ECU/PCM. This works well for the stock engine and transmission, but when performing a B series engine swap with auto transmission this becomes a problem. By directing the transmission controls to a separate transmission control unit, you are able to use one of our OBD1 AUTO ECU packages to run and tune your B series engine swap without loosing automatic transmission function.

Features:

  • Uses all OEM connectors and pins for OE quality and durability.
  • For use with one of our OBD1 Auto ECU packages ONLY.
  • Must use our P78 Auto TCU or equivalent separate OBD1 TCU
  • Must use a 94-95 Integra automatic transmission. Will NOT work with 96+ OBD2 automatic transmissions

The yellow wire pigtail (harnesses sold after 3/1/17) will need to connect to your shift lock control under the center console.

All HA Motorsports ECU's, products, and services include a One Full-Year VIP Warranty

QUESTIONS & ANSWERS

Ask a Question
  • Will this harness work with the original d16y engine and automatic transmission? As in just tuning the automatic d16y with the proper obd1 automatic ecu (P28,P06 obd1 automatic ecu)

    No, this will only work with a B series automatic transmission setup.
