well maybe it's different between the 2.0 and the 1.6, but i don't consider it two wires coming off of the negative terminal, b/c it's one wire from the terminal to the strut tower, then at that junction, another ground wire comes off of the strut tower and goes away to somewhere else, i don't really know what the other end is connected to. i don't consider that second wire to be a ground from the battery b/c it's not connected directly to the battery, it's simply connected to a bolt on the strut tower that is also connected to the negative battery terminal.
does your 2.0 physically have two wires coming directly from the negative battery terminal to a ground on the body?
