I have been reading that when hooking up a motor its best to use your true south. So my true south is 73.8 longtitude so I will just round up that I should choose satellite 74w. Horizions 2. But then I was reading on another site and they For example for New York City, the true south will be 180 plus 14 = 194 degrees on the compass. I am in New York City. since I do not have a compass I would think I should just find 74w with a meter and go on from there? Would that be the best way to do it or should I use a compass?

Cosmo,
Phlatwound and Ice are correct.
However, I think that a lot of folks get hung up on this issue when it should not be an issue at all.
Follow me here and take your longitude coordinate and that will be your true south "direction" to aim the at dish towards. There may not be a sat perfectly poisitioned there, so you and others may have to compromise.
Which Ku band linear satellite is closest to your longitude coordinate? That is the one that you will want to utilize. This satellite that you choose may not be in perfect alignment to be your true due south sat, but don't fret over this issue. Just select the closest one with a consistent signal.
Allow me to give an example from my location. I am at 96.4W for my site longitude. This means that my nearest due south sat is 97.0W, IA-5 (or now referred to as Galaxy 25???). The name of the sat does not matter, only the orbital degree position matters.
Your truest south sat will be 74.0W (Horizons 2) and the best TP and channel will be on TP 11734 MHz, Horizontal polarity, 6616MS/s Symbol Rate. This is the TP which carries the ONN (Ohio News Network or WBNS TV).
So, in short words, whatever your longitude coordinate is, that is the orbital position of your closest true south sat. Don't get confused with a few adjustments to your coordinates with the magnetic declination or other parameters. Your Longitude should equal or be darned close to the orbital degree of the sat. This is all you need, do not try to make it more complicated.
If your truest south sat has no good or consistent channels available and you have to utilize a sat that is a few degrees off, do not worry a whole lot about this. Yes, you will have to do a bit more work to align your dish to the whole arc in these cases, but it isn't too extreme. You won't be as far off as you might perceive.
The alignment of the dish becomes easier when you have accomplished it on your own a few times. It suddenly will begin to click for you and you will find that it is easy as pie!
Simply play around with it on your own for a while and get accustomed to your dish and your receiver.
