i know roughly where it should be but i am not 100% sure. I am fairly sure that its giving me the problem with the sensors, seeing as it feeds power to all of them together, and none of them are getting any!
does anyone have the part no for a replacement or a relay that would be suitable for replacing it.

Thanks Mike

 

for anyone looking for it, its under the driver side dash up the side as far as you can reach, you need to take apart the rest of the fuse holders as its a pain to get to. Not only that but you will need to get the bracket unscrewed to get it off.
DONT DROP THE SCREW!!! it dissapears!!! trust me!!!

 

for what its worth, my relay had melted inside stopping the contact from meeting, due to the short in the lambda.

its all sorted now and the car runs better than ever before so i am happy.
