green wire on aftermarket tachs are the signal wire i belive
there are four spark plug wires that run to the distributor..the fifth one is the coil wire
if it is a big power wire ( same size as the battery cable ) then it is the earth wire you should find that the battery has one wire going directly on to the engine or chassis there are different arangements the negative wire could be coming directly to the starter and if this is the case then the wire is just earthing the engine but in a lot of cases the starter is getting its ground from the engine and the engine gets its ground from the battery
