As did Cody, I installed 200 seats into my 5000CS. The functionality of the two
seat designs is the same although the calibration of the seat heater system is a
little different (200 seats run a bit hot when wired to 5000CS seat heater control
modules). My method was to cut out the seat wiring harnesses of a '90 200
and splice them into my 5k. Better, I think, to make the car electrically look like
the one the new seats came from rather than the other way around.

So I would do the same in your case. Salvage the seat harnesses from a 5k
and splice them into your 200 seat harnesses. If you would like, I can go through
my 5000CS and 200 factory manuals to come up with a wiring list. One thing
to keep in mind is that some of the seat wiring harness wires are electrically hot
even while the car is not running. Short story: pull the battery ground connection
when fooling around with the seat connectors.
