... immediately, disconnect the battery.
Now.
Then come back to read the rest:

Remove the driver's seat, disconnect and remove the CLU.
Open it up and remove the printed circuit board.
Place the printed circuit board in a shallow dish such as a Tupperware.
Cover completely with Isopropyl alcohol (rubbing alcohol).
Let it sit there an hour or two, while lightly moving back-and-forth so that the alcohol can get into every nook and cranny.
Then take out the circuit board and let it dry on its own.
Don't force-dry with a hair dryer.
While the board was soaking in alcohol, make sure that you dry the plastic enclosure and the connector and wiring harness completely.
Make sure the car is dry.
Clean out your (most-likely-clogged) rear drains next to the soft top's pivots (one on each side).
After all is dry put the ECU back in. make sure the small fuse is not blown.
Reconnect.
Put the seat back in and connect it to it's harness.
Reconnect the battery and test everything.
Enjoy.
Happy Boxstering,
Pedro
