nology wires & amp...Need Help?!?

ok ok heres the deal, picked up nology wires and the little amp that came with it, but no instructions,I bought them used. Anyway the guy said something bout hooking them up to my distrutor cap. Also any advise on which sparkplugs to buy, I'll be down there anyway so might as well change them. Mahalo in Advance :bloated:

i'd sell that setup to someone born yesterday and get a real setup from MSD, Crane, or Jacobs.
