After purchasing a headlight relay switch for my 1972 240Z, couldn't find where it went. Then looked up some old notes in the tech forum saying there isn't a relay for headlights in the 240. (I was having some problems with one headlight dimming but cleaned up some connections and it is much better now). So why does a company offer/sell a part that is not needed? I guess there must be a way to convert it to use relays. So it is worth it to convert it? Or just leave as is? If it is worth it to convert it, how is this done?
