Hi Serendipity! I am trying to troubleshoot a flashing light and alarm even though my convertible top is closed. Changed the rear bow lock already from Klaus (‘02 CLK55) and he had me check the microswitch on the front and I measured the latch and switch and they are within spec. So he sent me this message: The next step would be following the two wires from the switch in the front latch assembly to the controller and short them at the controller, but I don't have their pin-out. So he suggested I contact you for the location of the controller. Do you have a diagram of where the front controlled is? Thanks!
