Ah right that sounds a bit easier than feeding all the wiring from behind the dash through to under the bonnet which is how i had been told to do it by somebody else!
I will try and have a go later in the week, may have to come on here and ask a few more questions if i get any problems with it.
Some of the loom under the bonnet is damaged from where the car had a front ender, meaning the rad, intercooler, headlights and power steering pump were completely destroyed along with most of the wiring attached to them so will either have to look into repairing it or getting a new under bonnet loom made up.
