Where did you get the replacement wiring harness and CLP/SSM? Was it from a wrecked car? You didn't change either but tried to FIX THEM? THere is your problem. You need the items from a junked car, you cannot fix water damage to the CLP/SSM or its' harness.

All CLP/SSMs are the same, but the wiring harnesses are NOT the same. Tthe harness has to come from a Coupe or Roadster in the case you have a Coupe or a Roadster in case you have a Roadster. THere is an extra wire in the Roadster harness, the lock airline plumbing is the same, cept you have an extra airline for the console door in the Roadster, but this is tapped off the (I think) driver's door air line.

The reason they call it the "Central locking pump/security system module" is because it has the air pump to operate the door (driver, passenger, fuel) and trunk lock as well as the console door lock in the Roadsters; it also has the brains of the security system.

MORE INFO:
When you press the FOB, it talks to the SKREEM which flashes the turn signals. The SKREEM then tells the BCM to tell the CLP/SSM to lock or unlock. The CLP/SSM also flashes the fog lights/tail lights and operates the alarm siren. Your FOB is OK because the turn signals flash, your CLP/SSM is the problem.

When you press the button on the switch panel, it tells the BCM to tell the CLP/SSM to lock or unlock. Again, your CLP/SSM is the problem.

If water seeped down the wires enough to "rot the connectors off" it then traveled into the CLP/SSM and ruined the circuit boards. Again, your CLP/SSM is the problem.

SHould I repeat myself again or did I make my point?

I have lost count of the number of cars I've fixed with this problem, water leaking in there is a real threat to all cars cept mine, cause mine sits in the garage, period.
