This article exploits a combination of ECU pin locations and wire colors for all M/T '96-98 Civic and '96-99 Integra VTEC and NON-VTEC vehicles.
OBD2A PLUG CONFIGURATION

Below is an example that shows the onboard (female) connector configuration for an OBD2a ECU.
Take note of plugs: A, C, and D.
The blank connector (B) is only used with civic/integra vehicles equipped with A/T.

Get an obd1 p75 and you will not need to do any other modifications. That harness will plug into your car's existing wiring.
