I see that you have another post about the stalk switch electrics. Perhaps you might find the Sierra electric circuit diagrams useful in answering your questions. You can see these in the service and repair manual that you can try and download from the link below. Of course this assumes that you are using the donor wiring loom for your 2b. Probably the four wires that you have in the dome lights are for earth, side, main and dipped beams.  Looking at the wiring diagram, page 13.56 there should be a brown wire (earth for the side light), grey/Red (sidelight), Blue/Brown (common return for main/high and dipped beam), Yellow(Dipped beam feed), White(Main/High beam feed). Thats 5 wires, so I don't know what the sixth is, but you will see the colour and check with the diagrams. Also if the loom is still on the donor then of course you can just check out which ones are live when you operate the lights to confirm the diagram.

Just had another look, and if the sixth wire is Black it's probably for the fog light, which you will most likely not need (yet). Note that the High/Dipped beams do not appear to run straight to earth (brown) like the side light and fog light. They use the Blue/Brown common return.
