DynoJet Wideband Commander?

Alright, I bought the Commander and am in the process of installing it right now. For the power cable, it says to connect the red wire to a 12v "fused key on" power source? What would be the best wire to splice into? I basically bought the dyno jet to have accurate air/ fuel ratio readings. Not to tune with.
 
Alright, I have the Commander installed, but at idle and reving the needle sweeps from 14 to 18 ...bascially all over the place. I called my tuner and he said that he's had a few poeple with the commander and they had problems with it doing funky things. Have any of ya'll with one installed have these problems? Please help!

I'm probably wrong on this, but I have a friend with the autometer air fuel guage, it its all over the place, he was told that the guage should do this because the air/fuel isn't constant. So does this mean he was told the wrong info and his guage isn't working properly?
 
Well, I did some research and I read the same thing. I also heard that the airfuel gauge is only uselful at WOT. So I tried that and the gauge went to where it shoulda been. Just scared me there for a sec thinking that my A/F was every where.

You do not want the sensor heated up unless you have the motor running.

Look at your directions and I'd think you will find something along those lines.

I'd just find a source that goes hot when the ignition is in the run position.
