Hi folks. Just bought a 1976 SAAB 99 GL, and have begun work on it. Can anyone shed light on what relays are used, and for what? I cannot find any info on the fusebox. I want to have replacements and several are unmarked. One by Hella doesn't seem to exist online: 003 205-018. There is a Hella 003 205-016 and that one can be found used. My goal is to eventually replace all of them. Thanks!
