How to check Engine Code for '95 Lumina

The Check engine light came on the other day while I was driving my '95 Lumina. Is there a special trick to accessing the error codes so I can count the flashes and figure out what is wrong with it? I know with the '93 you can use a paper clip.... Also, once i coun the flashes where is the best source to look up what the number means? Thanks.

Call your local Chevy dealer, or go to the library and lookit up in a service manual.
