All the swapping sounds pretty doable. Just do one lamp at a time and you won't have to worry about getting wires mixed up.
The bus I just picked up in Texas doesn't have them. I needed them on my trip. I almost used my 8 ways then thought bring traffic to a complete stop wasn't a good idea. All of my other buses had them.
