its behind the clocks in the dash on the top of the speedo cable

theres a 3 pin multiplug coming off the top of the speedo cable, clip the black wire from the speedo cable side of the plug and re-earth it behind the dash somewhere, on the metal! :P

Shouldnt matter if its cut totally as long as somewhere along the line it has a good earth path, more earths are better than less!
