I should have documented the process but frankly, I don't want to mess with the camera again. For me, the X-T3 is in a fixed position and (finally) will always run on the dc coupler. I will say that 1) the rubber pad lifts straight up from the battery chamber but is tethered so doesn't come off the camera body and, 2) the channel is narrow and I found that while the cable on the Wasabi coupler just barely allows the battery door to close, the cable on the Neewer does not.
