I need to replace the earth cable in my primera running from the battery to the engine what do i need to do

Disconnecting either battery terminal will have much the same effect - if you have the radio code then fine but if you don't have it you can sometimes keep the radio alive by squirting 12V into the car through the Cigar Lighter socket.

Buy new earth strap - take off old one - clean body connection to make bright - put new one on - do up tightly and smear vaseline on.
