The negative to engine and engine to chassis wires are very easy to find on the VX - just follow the black wire from the battery down to the engine block, and you'll see another wire running from the same point down to the chassis. The positive to alternator is pretty well buried though so you might need to look at the manual to help locate it. Do you have the CD shop manual?
