Three screws hold the inner block. Removing this eases the task of threading through the board connector and insulated soldering work.

Not pictured is application of insulation to the soldered connections. This is necessary to prevent short circuiting and equipment failure. Options include heatshrink tubing, liquid electrical tape, or hot glue, among other approaches.

Cable retention and strain relief is created with hot glue as pictured. Sugru is recommended as a clean, strong, and aesthetically pleasing alternative.

The hot glue was applied two-fold: within the housing (through the rear cutout), then at the C-clip flange. The C-clip was screwed down atop the second glue application while it was still cooling.
