I cant seem to find a part number for it anywhere? Im talking about the relay that sits to the left of the fuel pump relay. Is it just a universal 5-prong relay? Any help is appreciated.

Okay, pulled the relay, as well as the old one I had on the shelf. Both parts are correct for a late M20b25. Don't know if correct for an M20b27.

I ran into the same issue as you online. Ended up going to a local European parts specialist, who found the DME relay for me. He thought the generic might work, until I pointed out that the little retaining hooks on the side of the relay needed to be present for it to stay tight in the receptacle.

A generic relay w/o the side bumps works fine. A tie-wrap can be used to hold the relay in the socket and that solution is much more secure than the side bump retainer.
The car makes it possible, but the driver makes it happen.
