Now that you mention it, the two switches do appear to be identical. It was literally dumb luck that I got the dimmer back together. I thought for sure I would be down for two weeks waiting for another.
Tip # 914, and this one is pretty obvious - the plugs and sockets inside that headlight bucket aren't exactly made of cast iron and bridge cable. One tug too many and it's all over but a river of tears. It would be a good idea to gently pull the wires & connectors fully out of the bucket before wrangling all up on 'em with the wire cutters and all. The connectors fit through the hole just fine, a little at a time.
This one issue I fortunately haven't found out about first hand - yet...
