Coil pack harness replacement

[ExiledWeegie]

hi guys, happy new year

ive just bought a coil pack harness repair kit as ive been getting random misfires for a while and havent been able to sort it and its doing my nut in, ive literally checked everything 10 times, simplified pcv system with silicone hose and aluminium check valve, deleted all the vacuum crap and check valves under the plate, smoke tested whole system and its all sound, done the coils and plugs, also done compression check and still getting misfires on all 4 cylinders randomly so now im onto the coil pack harness.

so ive bought this kit... is it the right one for me? 1.8t 20v auq, i couldnt see anywhere that it tells you what engine codes it works for so just took the plunge for 20 quid. also for anyone whos done this on the auq, the plug has 12 pins, 4 for signal wires, 4 for power and 4 for grounds, does the auq harness have 4 individual ground wires? i havent cut into it yet so just trying to suss it out. thanks for any help in advance.

cheers bud but I have no clue what I'm looking at there lol not great with wiring diagrams and stuff

I went out today and stripped back the tape and plastic conduit and its revealed 11 wires but the plug for the new loom has 12 pins, I found these pictures which makes it easier for me but still a bit puzzled why the pics and layout shows 4 grounds 4 power and 4 signal when I only have 11 wires.
