It's a dead simple fix mitch, I just popped down to SuperCheap got a $10 relay and plugged it straight in, 30 second job. Tested it and there is no noise when I plug the fuse back in. Jobs a good 'un!
Not too worried about it Kym, I'm actually glad I didn't have it if it wasn't right!
(Can I grab that shroud off you sometime tomorrow mate?)
