After run water pump

[mpboniface]

I have a 1986 CGT hybrid. I installed an MB engine with Lumenition EMS. After many frustrating years I am almost finished. I only need to install the afterrun water pump. Can someone please identify the relay or relays I need ? By the way, I am not installing into the original wiring scheme, giventhe CGT didn't have this pump. I will be installing it from scratch

I have tried everywhere to identify the relay or relays but have had no luck.
All help is most appreciated.
Thanks,
Miguel

From what I can see on the 'magic software', the 1988 Quattro used
part number 447 965 571A - Control unit For Water Pump, relay fan stage 1
in relay location 6. It says MB and RR engines, (I didn't think the RR was available in 88, so the MB would be the only possibility.)
