Typically you use a A-100BC cable ( http://www.analoguehaven.com/doepfer/a100bc/ ) to connect the two busses together. This also connects the left and right sides of each bus together. You can also connect the two bus boards with a standard 16-pin power cable. Just connect it between 2 unused headers (one on each bus). BEWARE- Make sure you have the orientation correct on the cable before powering up the unit otherwise you risk blowing up your power supply.
