I didn't miss the replies - I've been researching that thread actually that was posted about water in the trunk but I had hoped it wouldn't go that far to be such an issue, it would seem to me like this is a design flaw if it has been going on for 10+ years on the SLK models. Is there a recall on this so it is fixed properly? this can cause the battery to failure and electrical issues that obviously will cost a lot to fix and even then you're not certain if its done totally right because of the design flaw that it can and will eventually gain water back in that area of the fixed SRT spoiler getting leaky and whatnot.
I do have time to tinker around with it but I also don't want to break something in the process and I also need to be able to find a way to shut the alarm and the fog lights and side marker lights so I can work on the car without the alarm turning on since it does have that backup re-chargable battery in it.
Any options there?

These modules are not cheap, so look on eBay for one.
I would say that only this module is toast if it is soaked. The 'helpful and knowledgeable' tech will invariably run up the bill as he gets a cut of the profits on what he sells you. That's free enterprise for you, it's not free as you'll pay.
I have revised this post in light of a thread I found on a MB forum, maybe it sounds familiar, the fog and tail light problem is due o the cental locking module failure, see the thread attached.
Car lights won't turn off..Help! - Benzworld.org - Mercedes-Benz Discussion Forum
Here's an eBay search for the module. Buy a Mercedes one as the Chrysler part will soak you really good.

Thank you for that information. So my best bet would be depending on the results tomorrow is to get the car back home, find a way to disconnect the battery without having the alarm go crazy ( may be this is WHERE I Should get into the siren alarm area and actually just disconnect it ) and then from there I can work on the car while I wait for the parts to come in while my battery will need to be disconnected in the mean time and then re-connected if I need to drive it and whatnot, also, by doing all this, what would be a way to make drain holes in the area where water has collected so it can spill out in case this area somehow gets water tinkered in there, is there a how to guide on this? I would rather not drill holes in an area where I could splice a wire while doing that, thats a big concern..
