Where is the MAP sensor on a 93 honda accord lx or what does it look like, is there a picture or sematic that I can see?

I replaced the main relay, But how can I test the other relays to be sure the other ones are not bad?

It's likely on the firewall, just to the right of the fuel filter. It has a 3-wire connector going to it. A hose runs from the MAP Sensor to the top of the throttle body.
