What do these relay's do?

[BAZE30]

Hi,

I have an E30 S50 however I discovered a broken green/brown wire underneath one of the relay's and I'm not sure exactly which pin it should go back onto and wanted to make it went back on the right pin.

See the 3 relay's sitting on the strut in the below picture (this isn't mine, I pasted this in from someone elses as an example)

What do those 3 relay's do? Fuel Pump, unloader????

would anyone have a pin diagram. Google is returning American M3 diagrams so I can't figure out which.

thanks

The white relay is the main ECU relay.
The two black ones are actually 2 pairs of small relays.
One of them is for the fuel pump and the one next to it is for the starter.
The other pair is for the O2 sensors and the air pump.


If the broken wire is small, brown with green stripes, that one goes to the fuel pump relay pin 85.
If the wire is actually thick, green with violet stripes, that also goes to the same relay but pin 87.
To help you identify this relay, the other wires to this relay are red (pin 30) and red/white (pin 85).
