I currently only have side lights and can't get main of full beams to work. I have tracked back from the bulbs and there is no power to the bulbs. I am back to the fuse box and I found this wire unhooked (see photo). I have checked the wiring diagram and it appears it could be from E4 on the diagram. I am not the best Electrician but could this be the problem, as it is live when the ignition is switched on.
AFAIK the lights will come on regardless of the ignition being on or not. So unless someone has changed something, doesn't look like headlight wire. Could be wrong though.
I would test the lights work by hooking it up to any live fuse first and then worry about which terminal it came off.
It should go to terminal S on the headlamp relay, which means you need to disconnect the battery, take the fusebox off and reattach it. See other post here: http://www.thelatebay.com/index.php?threads/no-headlights.48395/page-2#post-860222
