Which wires go where??

Question

Need some help on wiring this 8330-752 control pack in my camper hooking it to a residential thermostat.  Where does the b- wire hook to? The options I have are Y, B ,O ,G the Y I have figured out I'm going to hook the high fan up instead of putting in a micro switch. The options in my control box are GL, GH,Y,B- . I would connect b- to B but it says B is to the heat acting reversing valve ... I don't think that's where it goes. G is the fan control relay on the thermostat but B- on the control pack says neg 12vdc so I'm stumped..,[img][/img]

It's. A Robertshaw 9500 ... I don't have any wires ran yet my Coleman Mach has the knob controls on the roof. My heater is running fine with this thermostat but I want to run my ac off of it. Do I have to run a ground wire from my battery is that what the -12 vdc is? I just bought the 8330-752 control pack to switch out and run the thermostat wires myself.
