actually not easy to find Australian DIY on the net because of safety issues and no proper sparkys will divulge info like that openly. You are supposed to get a licensed sparky to do any kind of electrical work like that. That's why all HPM products do not have DIY instructions on the pack. I had that problem when I had a broken light switch.
Best way is to take a photo of the old plug and use that as reference to wire over to the new plug. It's very easy to do but I'm not a sparky so don't take my advice for gospel
