You will need more info on how you intend to run them. Batch fire, sequential ect.
A switched live to all four and the ecu will earth them.

It looks similar to a megasquirt set up.
You have a relay switched by the ECU (PIN 7) this relay serves power to the fuel pump and injectors (pin 87). Take the red/yellow wire and connect it
to the same pin on all 4 injectors.
Then you have two outputs pin 19 and pin 20, take one and wire to injectors 1 & 2, take other and wire to injectors 3 & 4.
Just had a quick look at mine I actually wired 1 & 4 together and 2 & 3 together. This is batch firing - bit like waisted spark.
You need a cam sensor to do any sort of sequential injection i.e. 1,3,4,2 - which the Duratec has but you ECU needs to be able to do it too.
