Ignition Key Switch

WARNING: This page is about a different car, the 1991 Honda Civic and 1990 Honda Civic. However, it is still accessible from the selected car via links, so may be relevant.

Remove the dashboard lower panel, then disconnect the 5-P connector from the main wire harness. See Fig 1 .
There should be continuity between the BLU/WHT and WHT/BLU terminals when the ignition switch is turned from "II" to "O" position. There should be no continuity when the ignition key is removed.
