Connector to J4 from touch screen can be put on two ways. Which is correct: violet wire to lower right (vcc) or upper left (batt 1).

It is the only connector on the unit that is not keyed and on which they did not put any black goop!

Connection is not to J4, but J5, which I missed. J5 is marked White Wire, though wire is not on outside of connector. With white wire near white wire marking on board, it works fine.
