I'm afraid the A-143-2 does not connect to the bus.
On Doepfer's DIY page ( http://www.doepfer.de/DIY/a100_diy.htm ) in section 4.1.4 it list the Doepfer modules that connect to the buss:
Only the modules A-110 (Standard VCO), A-111 (High end VCO), A-140 (ADSR), A-185 (Bus Access) and A-190 (Midi Interface) have access to the CV and Gate signal of the A-100 bus. A-185 and A-190 are used to "write" the bus, i.e. they output the signals to the bus. A-110, A-111 and A-140 are able to "read" the bus, i.e. they pick up the signals CV (A-110, A-111) resp. Gate (A-140) from the bus. For details please refer to the user manuals of these modules. If other modules should be able to "write" or "read" the bus the module in question has to be modified.
It shows the pinout of the bus and you can tack the gate wires to the normalizing pin on the gate in jack on the A-143-2. I don't have my rig in this room to pop it open but make sure the normalized pin is not connected to anything else before doing this. In some systems the normalized pin is also connected to the main pin as an easy way to reach it (traces came from that side of the jack sort of thing). I wish all the normalized jacks in the system had empty pads or holes next to them to make this easier - i understand all holes cost money though.
