Just to let you know that I managed to get the job done - thank you for the diagram

.
The only issue I had was the headlight washers not popping up once the bumper was back on and instead spraying the inside of the engine bay when activated! This caused the EPC light to come on and the car to go into limp mode for some reason, but after letting it dry out for half an hour, it started and ran fine with no warning lights

I have absolutely no idea what was wrong with the washers themselves though, as after starting the car up again a couple of hours later to check for warning lights, they decided to work again! Not that I'm complaining as it's saved itself a trip to the garage!
