I have seen on line how to use a paper clip to pull CEL codes in my 1994 Civic. My problem is that I can't find the proper port to do so. I have looked under the passenger side dash board and cannot find a 2p plug. There are two fairly easily accessible plugs but they both have more than two wires connected and multiple ports. Not sure where else to look.

Service Check Connector (SCC): Reading OBD-I Codes

When the Check Engine Light (CEL) is on, it will be necessary to locate the 2-pin Service Check Connector (SCC) on OBD-I (pre-1996) Hondas. It is normally located under the dash, approximately 1 inch (2.5cm) from the right kick panel. Take a small screwdriver and carefully pry it from the rubber mount. The other 3-pin connector in the rubber mount is the Data Link Connector (DLC), which should be left alone. Jump the SCC with a paper clip, turn the ignition switch to ON (Position II), and count the number of times, if any, the CEL flashes. Reference a Diagnostic Trouble Code (DTC) chart to identify the code being displayed. The SCC is also jumped, when an induction timing light is used to check engine timing.

After troubleshooting, turn the ignition switch OFF, remove the jumper wire, and reset the ECM, by removing the BACK UP (7.5 A) fuse from the under-hood fuse box for 10 seconds. Disconnecting the BACK UP fuse cancels preset radio stations and the clock setting; therefore, they will need to be reset.

Does the CEL come on for 2 seconds and then go out, when the ignition switch is turned to Position II? If not, the ECM may be bad. If that's not the case, have Honda diagnose the ABS and, particularly, the SRS problem. Repairing SRS problems can be lethal, if you don't know what you're doing.
