Just remember to unplug yourself before getting off the bike. Heated vests are "God Send" in cooler weather.
The connectors that Gerbing uses seem to be very sturdy and will pull apart smoothly should you forget to unplug. I've done that at least once or twice, and the plugs disconnected just as they should. The Widder plugs are less sturdy, and I've had the wire pull right out of its plug at least once, instead of the plugs disconnecting.
I actually have had to use my electric vest a couple of times when touring in August. You never know when you'll encounter an early cold snap, particularly if you are at high elevations or riding after dark. They don't take up much room to pack, so I never tour without them.
The basic harness and connectors work so well, I really don't see any advantage to using the "cigarette lighter" connector.
