Wiring diagram for a 16v 1.4hdi

Hi , can anybody point me in the right direction for a wiring diagram for a 54 plate 1.4hdi 16 valve please. I have an intermittent problem of the vehicle randomly going into limp mode . The code that seems to be coming up s P2147 which I believe is injector one short to ground or some Google answers say it is injector supply low voltage . I suspect possibly a wiring fault as it started a few days after the car had a new heater water pipe fitted which involved removing airfilter etc . Injectors have been checked and swapped around but it still comes up with the same fault. I want to check out the wiring from ecu to injectors as the injector molded looms are like rocking horse poo second hand and also unavailable new now .

Hi kevmean.

This one hows the injectors to ECU but doesn't show any of the interconnects.
Injectors are 1331 to 1334 and the ECU is 1320.

Thank you for that , hopefully I can make a start checking the wiring from ecu to injectors now
