I stupidly took my SRT6 to the dealer for them to do some minor work on it. I got the car back and the steering felt off, so I removed the lower dash cover to have a look. Well, I found that the steering column was not bolted in! I called them to tell them about it, and they apologized and towed the car back to their shop to fix it.

They called today to let me know it was fixed and they apologized. However, while I had the lower dash cover off, I also noticed two wires just hanging there. One was a brown wire that was taped off (guessing some kind of ground based on the service manual showing brown wires for grounds) and the other one was a black wire with a switch on it. The dealer said that they didn't touch those and that they are for some kind of aftermarket part that must have been removed. Well, I bought my car from the original owner who was a fairly older gentlemen that said he never did anything to the car except drive it and change the oil. I think the switch also had MB part number/markings on it. So I'm thinking the dealer doesn't know what it is and are trying to cover up their lack of knowledge.

I took a pic of the brown wire and the switch before I sent it back to them for fixing. Here's the pic:



Can anyone tell me what this switch is for? I've gone through service manual trying to pinpoint it, but no luck. I'd really like the dealer to fix it if it is indeed a factory part. Or at the very least, I'll fix it myself once I know what it is!
