Hey Mark.

Thanks for the warning. Had seen your post in the archives about that.

I was curious of any differences between headlight switches:

251.941.531B and 251.941.531M    e.g. is switch with "M" suffix able
to handle more amps?

I have a spare  251.941.531B switch from an early model Vanagon and
thought it might be ok as a spare on my '88.  (I would compare PN's
and pin 1 location)

The description in this Van Cafe page shows the two older switches I'm
curious about:

But your point will be heeded and is important!    :)

Neil.
