Fuel pump control unit wiring

[fiat]

I need to know the wire positions on the plug for the fuel pump control unit. I bought a 1991 Q45 front cut to use the engine in a Fiat 130 Coupe. I have just aquired the fuel pump control unit but I need to know the positions of the wires in its plug. I have a wiring diagram so I know the colors of the wires that run to it but not there postions in the plug.
