Wiring diagram help needed!

I'm trying to find out which of the relays in the ECU box are responsible sending ground to the fuel pump relay. It's either 373, 291 or the other one in there... 395 I think?

Unfortunately, I do not have a Bentley, and I'm trying to diagnose a "no fuel pump relay signal" in 20 degree weather
