I found about 10 old street lamps that are 400w HPS lamps. As a matter of fact they are exactly what i bought from the inside sun company for $100. I gutted all of them . I got the ballast, housing and bulbs. I have looked for instructions on how to wire it but they just don't make since to me. I have three sets of wires three positive three negitave and three ground wires. I know one goes from the ballast to the bulb and one goes from the ballaast to the plug but whta the hell is this other set for? Do i need them. I am trying to get them all set to sell for really cheap on e-bay but this third set of wires is throwing me off. any advice would be great!!!
thanks
