Might I suggest, instead of just electrical tape, using a small plastic Project Box from radio shack? drill a couple holes in it for the wires. Foe even extra security, fill the box with epoxy or silicone, or even hot glue!

That's a really good idea...never thought of it.

Does it matter if your stereo amp positive wire is attached to the B+ wire or to the positive terminal???? I did exactly what you said in the directions. I get a negative 30 amps when I turn my key to radio only. However, when I start the engine it stays at zero amps. I turn on the lights, hi beams, AC, and radio full blast and the gauge will go negative for a split second and then jump back up to zero amps. My battery has never died before and isn't dead now. What do you think?
I tried my stereo amp wire on the positive terminal and the B+ terminal, and the gauge is the same regardless.
