Can anyone tell me where the main relay for a 1992 honda civic is located at picture would be great if possible and can you tell me if I can test the main relay to see if it good before replace it with a new one thank you.

Left of fuse box, wedged against left kick panel and above hood latch. Remove fuse box cover and lower dash panel for access.

On older Hondas, you should replace this problematic component.
