Crimped 13 blue (14-16 ga) Faston terminals onto 25 black ground wires: (2) 18ga wires at each terminal, (20) 22 ga wires with two at each terminal, and (3) 22 ga wires at one terminal, creating 13 total terminals. Connected to the 20 tab ground plate. Used nylon sleeve to protect bundle, plus added black heat shrink tubing at each terminal for some stress relief adjacent to terminal. Pending tying several wires to each other to provide better vibration support.
