How do I get power

Hi. you can connect it to power batter directly by postive and negative wire . rather easily use, plug & play

how long is the wire on the led strips?

Thank you for your question, the led strips are 12'' long.

I need wiring instructions you said it would come with package but it did not also package was cut open and covered.

We are so sorry for that.Our workmate maybe forget that we don't have wiring instructions in paper at present.If you have any queations about the wiring,pls don't hesitate to tell us,we will try our best to service you.Hope you can understand.many thanks!
