Not that I couldn't be wrong, but I thought I'd figured out that N59 diag module was the silver box with the securing knob on it under drivers dash left of steering column? Per this diagram: http://ww2.justanswer.com/uploads/PE/peterpete190/2013-03-08_161437_diagnmodule.gif

Far as I can tell, big yellow sticker under hood saying it conforms to all fed and cali smog, this is a california car with the OBD stuff.

Found the SRS light socket, good bulb, no light on key on. Just like the CEL.

I ordered an OVP just on principle.

Miracle of miracles, that appears to have done it.
Thank you!

Still no SRS light but I'll cross that bridge a little later.
