I am here working at the DataCenter working on the BJ's. I have 12, want to put 2/case.

Where do I plug the motherboard power for the 2nd BJ into on the Power supply?

There is one port labeled "MB" on the power supply. It is already taken by the first BJ.

Thanks
On the BJ, there should be 2 sets of PCI-E cables coming out of the PSU, and one 5-pin control cable.  One of the sets of the PCI-E cables along with the 5-pin connector are already connected to the existing (top) board.  The other set is zip-tied up by the PSU.

You'll need a chaining cable (16 pin ribbon) and the screws/standoffs to add 2 boards to one BJ.

Once you have that, simply mount the second board, connect the chaining cable from the top to the bottom board (using the 2 closest 16 pin connectors), MOVE the 5-pin cable to the second board, and then connect the spare set of PCI-E cables to the new lower board.
