Got no problem doing that just trying to work out what i actually need, as you can see theres loads of types of wiring harness and my brain has refused to function all week.

In my opinion, which isn't very much :lol
But taking into account of your poor lights (HID'S) you've had I'd try and get one supplier to supply you a full kit i.e. 1 x H1 and 1 x H4 with all the corresponding ballasts and wiring.

I know you've got loads of ballasts and bulbs lying around but your problem may be none are actually compatible with each other. So I'm saying you might need to just put them all to one side and get a set from a supplier.  They're are plenty that will supply you a set like this. The added bonus of doing this, is that, if they fail/don't work the company should help you get it sorted. When you mix and match stuff, no one will stand by the other stuff you got from somewhere else.
