I decided that my poor soldering skills work better with a gemma. That and I ordered two more gemma boards. Wired through Vout, D1, and Gnd. It works perfectly and only needs three connections. I put heat shrink on each end--three small pieces to keep them from moving and one large piece on the disconnected end. I can conclude it was the trinker data line because I tried the power for the far end JST plug before desoldering it and it worked just fine.
