99-00 Civic Auto to OBD1 Auto ECU / TCU Harness

Item# OBD2BCIVIC-OBD1AUTO
$249.00

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.
    Feautures:

  • 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

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