Also, I ordered the display and also a backlight. I installed the lcd, but don't see where the small backlight goes. I powered it up and got a brief small display on the lower right hand corner of the screen...than nothing. The system booted but no video. I am curious if I should replace the inverter board? Can anyone assist me in troubleshooting this? Thanks.

I suspect that the small black wire is a ground (black is usually a ground designation.

You might find something here
"LCD screens require the use of an inverter to supply power to the screen’s back lighting. Backlighting is used in smaller LCD screens such as laptops to produce higher brightness and readability factors".
With that said, if the inverter was bad, you would still see what was on the display. It would be very dark and sometimes the use of a flashlight would help "show" you what was on the screen. So if you are not "seeing" anything, then something is still wrong.
