So, I built the full length blade and the LED's do not turn off... Attached you will find the pictures of the connector (http://drive.google.com/open?id=0BwqZ0qtAgdt_OVE0Qk4wamppdFk). I used a 100 ohm resistor to prevent data leech, and a 3.3 kohm resistor for the blade ID. This was entered in the to blade array. When I get a chance I am going to check the blade ID and resistance in the serial monitor..

The connector end looks good, but I'm not sure about the LED hookup. The pictures aren't quite enough to show me what is hoked up to what, but it looks a little suspicious to me. Are you sure the yellow lead is hooked up to DI (data-in) on the LED?
Yes, I am sure it is. I checked the pin out on the ones I bought and it seems to be correct here is the link to them (PL9823 F8;8mm round hat RGB LED with P9823 chipset inside;full color;frosted-in) . I added pictures of the connections to the LED. I also added pictures of the blade ID from the serial monitor. One thing that is not expected is the 2 led blade has a blade id of 2.2kohm and the long blade of 3.3kohm. When I plug the full blade in it says its the two LED blade (see pictures http://drive.google.com/open?id=0BwqZ0qtAgdt_OVE0Qk4wamppdFk)

Ok, this is going to hurt....
That page is super-confusing.
The headline says PL9823, but there are no less than three different pin-assignments listed on that page.
One is for PL9823, one is for PL9834, and the third one I have no idea what it's for.
If we assume that you got what you ordered, (which I'm going to assume is PL9823) then only the image containing the PL9823 datasheet is correct. (PDF here:
https://cdn.instructables.com/ORIG/FW0/YN1X/IHDUL683/FW0YN1XIHDUL683.pdf) This datasheet specifies that DIN is next to VCC, which is not how you have it hooked up in the image.
Assuming that PL9823 is in fact what you have, and all you did was to get DIN and DOUT backwards, you can fix it by turning your string around and feeding in the data from the other end...
