Sometimes not all slots are used on relays since they have multiple applications (car manufacturers use the same part in several vehicles sometimes, especially small electrical parts).

What you might try is to go to the auto parts store with the relay you found, and request the part that you're trying to replace...if they match you're in business.

I know I didn't answer your question directly, but I'm not one of the under dash guys.... hopefully they'll be along shortly.
