Resolved by Xuven!

I have taken a couple of years off of this omnibot 2000 build. I kind of get stuck, frustrated and quit. Then every no and then I comeback and look at it again. I have watched a lot of the videos people/bot have recommended and I'm still stuck. Mostly this is because I'm not an electrical engineer...LOL I know how to take things apart and monkey with stuff. I can solder and follow instructions but this project has stalled. My main issue is that the videos go to fast and are not detailed enough for my limited knowledge. So here is where I'm at. How do I wire the hbridge to the ezb and battery and how do I wire the 8 motor wires to the hbridge? Here are a couple pictures to show what I have going. Thanks in advance for any advice.

Thanks, EZang60. I got the hbridge figured out. Tonight I got the I2C cables, camera extender and jumper cables set so I was able to connect the BlinkM leds to the eyes and mount the camera. I'm waiting for the servo mounts that Xuven suggested and I will get his head right. Baby steps but I'm happy with our progress. Here are some pics of the eyes working. Cheers! CMC

I had some difficulty doing the verticle servo so I just opted for the left-right movement only The good news is that I will be able to use the other servo in one of the arms. I was worried that I might burn out a servo or my kid might if we didn't hit an init script before starting. Even then every time I plug in the EZB the servos they all make a move to the right or a 0 position. So I did this repeatedly and that's when I got worried about the vertical servo that might get hung up. I figured that the left to right I won't have to worry.
