Howdy, Started getting the door ajar issue in the rear driver side door about two weeks ago, and now it won't clear no matter what I do. I'm interested in splicing into the sensor wire and adding the magnetic switch described elsewhere later on, but for I now I'm just going to ground it to the frame and clear the warning. All I need is to know which of the wires is the sensor wire, as I can't seem to find a diagram. Pic is the panel and the four wires coming out of the bundle. Thanks
