Forgive my nubee-ness. But Beyond straight wiring, I don't know what to do with it. Looks like there are 3 leads that should be soldered on a small circuit board. Another source says the 7812 needs a heat sync for any draw above 50ma (these draw 150ma)
How does it all actually hook up to the battery leads?
