Well, big thanks to Bambam(Pete) for stopping by and taking the time to let me plug my cluster into his bike. Sure enough, it lit right up, so i had some wires to trace!
Also thanks as always to Ray for helping me figure this all out. We started by looking for a diagram withe the pin-out for the plug on the back of the cluster. well, thats tough to do. I ended up with this one...

I used that and matched up/ traced/ verified the wire colors and made my own pin-out for the plug. I figured id post it here as it might help someone else in the future...
***This was the plug on my bike, which could very well be different than yours as mine is a theft recovery bike and who knows why it had this problem***

...that would be the plug.
1. Red/ white -to fuse-10A-Fuel pump
2. Orange/ Green -to fuse-10A-Signals
3. Orange/ Red -Speed Sensor
4. Brown/ Black -to ECU
5. Red/ Black -Fuel Pump
6. Green/ Yellow -Oil press
7. Blank (on mine)
8. Blank (on mine)
9. Black/ Green -Fuel Pump
10. Yellow -High beam
11. Black -Left signal
12. Green - Right signal
13. Pink/ White -Speed sensor
14. Blk/ Green -ECU
15. Blue/ Black -Neutral switch
16. Black/ White -Ground
So after looking at the diagram in that link, and reading some posts from this forum i noticed the cluster should have 2 grounds. Well, we got the idea that we should try and add a ground to one of the missing pins, and sure enough... the cluster lit up. So i wedged a wire in the pin (8) and spliced it into the gorund pin(16) until i can ge the proper pin to repin it.
Why was my plug missing a ground? i have no idea. but maybe the pin out is different between years, maybe the cluster is from another bike? but the mileage seems accurate checking the condition of the bike and such.
So, atleast i got it working... even though it didnt make much sense as to why in the first place.... haha.
