Amp Problems...help

This is for the amp that hooks up for nology wires (sparkplugs) I know this is an audio section but figured you wire heads could help me out...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:

Daym... nology is expensive... well not sure how to hook them up, but I recomend bosch spark plugs...
