Yes, wiring must be disconnected and they do disconnect easily (in most cases). I've never tried to disconnect at the swithches and would advise against that as you'll have to solder them back in. Instead, you should disconnect and the wiring harness leads inside the headlamp bucket. Remove the lamp from the bucket and just follow the leads from the bars and be sure to label everthing well on either end. Do one side, then the other to keep clutter and confusion to a minimum. Grab some painter's or masking tape and a fine tipped permanent marker and label each side of each wire that you disconnect (right red (on both the wiring harness side and the wires through the bar side), left green, etc.) It is time consuming, but it is neccessary to get everything back together. Again, just be patient. Don't rely on wiring diagrams due to the fact that these bikes have been assemble and disassembeld god only knows how many times in the past. Sometimes different colored wires are in play with each other becasue of replacements, etc. Labal, label, label. Sometimes pictures help too, if you have that option.
In this picture, you can see the bits of blue tape inside the bucket that serve as the labels:
