hi, the other day, I install a scanner for my car, and they said that one wire should go to the battery and one to the chasis, i got it to work, but then my friend said that i shouldn't connect the battery wire to the battery and it could be dangerous, so he told me i should put it in the fuse box, but being a total girl that I am, I don't know how, so can anyone help me put the wire into the fuse box? how can I do it? thanks..by the way, i have a 1996 Accord.
