I think the serial version (BU-355) already includes a wire for the PPS. I
don't have a handy pointer to the appropriate documentation. It's the
yellow/NC wire in the picture Rex provided.

I'm a bit suspicious of the S4 version but don't have any details. gpsd has
troubles with it. It feels like a firmware bug to me. The SIRF chips are
very popular. I expect things will get sorted out eventually.
