Infamous Porsche option codes

[ED3777]

Just purchased a 2000 arena red Boxster and am wondering about some of the option codes. I've visited seveal sites and this is what I've gleaned so far. If anyone can fill in further from their own car or another source, I would appreciate it.
Code Option
139 Left seat heat
222 traction control
232 unknown
340 limited slip diff.
396 17' wheels
437 unknown
438 unknown
446 wheel caps w/colored crests
454 cruise control
490 Hifi sound w/6 spkrs and base reflex in doors
502 unknown
535 remote control alarm
537 unknown
550 hardtop (has disappeared)
551 windstop
584 unknown
696 AM/FM radio w/CD player

My guess is that the memory seats are options 437 and 438??

Thanks.
