Thanks for ur reply, i think i may have trouble getting the battery out as i have an itg maxogen right up against it. Also how easy is it to get from behind glove box to drivers footwell?
i just took the carpet away under the glove box, and there is a sponge type material you can remove too, you will be able to see a port through into the engine bay, i stuck a screw driver through (quite big/thick one) then a smaller/thin one, i then put the boot pipe over the thin screw driver, covered it in duct tape, and pulled through...oh and wd40!
Just be careful with A the wires under the passenger seat and B the port that you decide to use, if there are already wires running through there you dont want to damage anything.
