[QUOTE="hispls, post: 8790204, member: 614752"] Yes, you want it ONLY live when your car is running. Google your make/model and tap in under the steering column or wherever is convenient. If you already have one right at your alternator you could use that but you may opt to mount the blue box elsewhere like under a seat or in the trunk. I have seen people with these mounted under the hood but I'd guess not being somewhere quite so hot would probably be preferable. 16 gauge should be adequate, I used larger mainly because the beefier cable is going to have more rugged insulation and will be less likely to fail over time from any sort of wear or deterioration. If something goes tits up with your connection your alternator could start charging extremely high and boil batteries and possibly destroy a lot of other stuff in a jiffy so whatever, just make sure everything is solid. I used a T-tap under the steering column for the switched power and just trimmed down the 8 gauge enough to fit it into the yellow crimp terminal to plug into that. You are correct it's only the potentiometer on a wire to control it. You'll need to buy a voltage display separately. I use audiopipe branded one that seems to work well enough and we used the Stinger branded one in my brother's car since we got it for a good price from the site we bought all his cable and stuff. There's plenty of voltage display options so take your pick. If you have different voltage at one point in your system than another you're doing something terribly wrong. Wherever you pick to monitor voltage should all be showing you the same reading. Electricity moves at nearly light speed and we're aiming for near 0 resistance anywhere in the system. Even the cheap ones should do and your voltage may wiggle around a little bit with weather and battery state so it's good to be able to have a display and keep an eye on it until you're confident it's in a safe place. All batteries are a bit different tolerance for voltage but generally anything above 14.8 will hurt them rather quickly so ideally you don't want to ever see numbers above that. [/QUOTE]
