Look inside the lightning socket on the bottom of your iPhone 5. Use a bright light if necessary. Notice there's only contacts on ONE SIDE. Therefore, Lightning is actually an 8 pin connector ONLY. Not a 16 pin. All you have to do is wire each side of the plug the same way from left to right and you don't have to worry about reversal. Did we just fall for thinking the lightning connector is more sophisticated than it really is?
