I am trying to troubleshoot my ignition system for a 1990 honda civic using TXGREASEMONKEY notes. #3 says jump the 2-P Service Check Connector with a paper clip. What does this mean? Explain how I do this please.

See if this helps:

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 (2.5 cm) 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.
