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.)

rr available from 88 in the home land ,if you still have not done the pump i would relay it to the fan live that would kick the pump in when ever the fan came in and a nice easy job
