I wanna know what wire does what. for example the brown/green wire is the oil pressure switch. you follow? you might think im being lazy but iv bound up my loom before i had the diagram so i dont wanna unbind it to trace each wire

, I wanna identify them buy coulour first. By the way i have not yet got the loom connector but i was gonna use one from a spare injector rail loom as i think its the same. Can you verify?
