Your Klima relay is very different from mine. I can't reduce the photo file size to attach it here but try this link:

http://photos.yahoo.com/bc/tabijan/lst?.dir=/87+300SDL+Klima+Relay&.src=ph&.order=&.view=t&.done=http%3a//photos.yahoo.com/

or go to photos.yahoo.com/tabijan and look in the 87 300SDL Klima Relay album. I have no reason to believe this is the original Klima relay.
