I have searched the forum before asking. I pulled up 3 screws from the plastic cowl to clean out the drain and found a plate/board 1/2” x 2” with two wires attached to it laying at the bottom of the cowl gutter? What is this?

 

Photo is worth a thousand words.

 

Found out where it goes but not sure what it does? It snaps in underneath the black plastic cowl on the far passenger side.

 

Wow, I don't recall seeing anything like that in mine when I repaired/replaced my failing siren(s) batteries. BUT, that given, does it have a MB number on it? I noticed the plugs on the rear have MB numbers but I think that is just the plug MB part numbers. I also could not quite make them out to research them to backtrack. Could you please look for a molded MB part number anywhere on the part? An old toothbrush lightly scrubbing off the part might reveal it. That should reveal exactly what that part is (and for). Thanks (Quite a strange part I say).

Could it be a terminal block for the two W/W heating system (W/W jets are heated)? I wonder instead of running them through a grommet, they just created a terminal block for easy access/replacement. Total guess though.

I am guessing it has to do with windshield washer nozzle heating too. All put back together now. Hate to try and unclip the wired block. Thank you all for your info.
