I just put in a new Jamma Harness and now I am not able to tune in the monitor. Please see the following video. This is the best I can get it...

Check your sync connection at the monitor. Looks like you changed it with the rewire.
 
Please see this picture to see how it is wired. From my Jamma harness, I wired:
- Jamma Blue to Monitor Blue
- Jamma Green to Monitor Green
- Jamma Red to Monitor Red
- Jamma White to ??
- Jamma Black to ??

There is a black and a white wire inputs on the connector to the monitor. However, I believe that the black wire from the Jamma harness is for a ground and I don't see where that should go when connecting that to the monitor. Also, where should the white jamma wire go?

Thanks!

It should be Red,Green,Blue, Ground and then Sync on the last pin at the end.

So from your picture you have everything right except the ground (black) wire is in the wrong place. It should be right beside the Blue wire
 
The ground is fine where it is. What game are you trying to sync this to? Currently you have the sync on only one negative pin. Sometimes this is fine, other times it will not work. Try moving the sync to the next to last pin, and if that doesn't work try jumpering it to both of the last two pins.

Also, have you tried adjusting all sync pots?
 
Look closely folks. He has a 9-pin video connector. That means ground is on pin 7 (key) and sync is on pin 9 (-vsync). You can see the 10th pin (-hsync) not connected.

You need to move the black wire to the spot (pin 4) next to the blue wire, then cut the connector between the black and white and position the white wire so it is on pin 10...
