keep it clean relays?

anyone running keep it clean relays? I just got some in cause my viairs went bad and these have 5 blades instead of 4. there's an 87 and 87a. just wondering if I should wire them up the same as a 4 blade and just leave the extra one blank???

yes, leave it open, 87a is just the normally closed contact with pin 30, meaning the two are connected when the relay is OFF and pin 87 and pin 30 are connected when the relay is ON. No connection needed.

alright cool, thanks for the help. appreciate it
