If it's the parallel LCD that Parallax sells (here), then look at the webstore page on the product for links to documentation and sample code and wiring.
As a general comment, you seem to ask for a lot of help and give very little information until asked repeatedly. That's a very poor way to ask for help in a support forum like this one. It's also impolite to use large fonts and it's strictly against forum rules to post the same question in more than one forum. If you really want help, it's best to ask specific questions with a lot of related information, like which LCD you are talking about. Include a link to a datasheet or other documentation. Explain what you want to do with it. Show us what you've done so far or what you've learned already. Include the source code of any experiments you've done so far and what you've learned. Describe what you don't understand or where you're confused.
