6-pin Relay?

[ROWSC]

I want to install two factory looking relays on my SC's fuse box to power the headlights. The gauge of wire used on the replacement factory type relay sockets is too small to handle to current. I found what appears to be a factory relay socket, but it requires a relay with six pins instead of the standard five. It was attached to an AC unit from an unknown specified Porsche. Is this from a later model car? What relay part number do I need?

Thanks,
