I just got a trailer hitch off craigslist (for free!) to fit onto my '89 westy.� So I am about to embark on the wiring and have read a little about the necessity to convert the independant bulb system to a common bulb system which most trailers use.�

I saw this product at schucks/kragen:� Hoppy 46155 - Electronic Taillight Converter Kit; Universal; Independent Bulb System Tow Vehicle To Common Bulb System Trailer

is this all I need?� It looks like the exact same product that Terry K sells for less than half the price but want to be sure.� We do not need an indepedantly powered system do we?

Thanks,
