G'day mate! I"m from the States ;) I am thinking about upgrading my Electrical System to 0 Gauge wires. For those of you who don't know what the Big 3 is... http://www.stevemeadedesigns.com/board/ind...showtopic=13280 Hopefully there are some people on here with my type of car that knows what it is. For those of you who have done this with my type of car, where did you ground? Was there a specific existing place that you grounded to so that you didn't have to drill any holes? Also, where on the engine block did you connect your wire?
