Many LCDs now a day operate on the same parallel protocol... If you take a picture of it maybe we can figure out if this is true.

I figured it would have a standard and i tested that but I found that power and ground were different than other pinouts i have seen but still here is the pictures.

According to http://www.topwaydisplay.com/TechnicalInfo/SimularModuleChart/index.htm your LCD is compatible with TM202J.
A quick search on TM202J gives this http://www.datasheets.org.uk/pdf-datasheets/Datasheets-37/DSA-734518.html
Looks a lot like your display.

The pinout should be the same as for any other HD44780 compatible display, it's only the physical arrangement that is different.  This 2x7 (or 2x8 with backlight) arrangement has been around for decades but the inline configuration is a bit more convenient for use with solderless breadboards.

Very true Don. I have a bunch newish 40x2 displays that I don't use for the same reason. It's too hard to use on breadboards. If you have an old floppy or hard drive cable, you can connect it to arduino without a breadboard.

I understand that you can plug them right into the end of a 'mega' as long as you program the appropriate pins to provide power and ground.

HAHA, OP, I had a dozen of those one time. Surplus galore on those things. I never got the chance to use one, long story :^(
