Standard there is no relay installed, but there could be installed an aftermarket 12V relay.
I'm currently in the process of installing one.
2 options: Socket 6 and 7 or they have been installed in their own relay carrier in an aftermarket part. The relays that I bought came in their own relay carrier. I want to have mine installed in the OEM relay support, so I'm waiting on 2 relay carriers that fits in the original relay carrier, so I can properly install them
Look at the link below.

I hope this helps.
