Wires!

One bug down!

I had Gates reassociate their hotspots whenever the gate moved. I also reassociated hotspots whenever they were moved. Problem is, Hotspots are placed relative to Objects, so they never move. The exception is the tail end of the wire. So, the Hotspot on the wire's tail associated fine, but the one connected to the head was never told to reassociate, so it would never connect to anything. Adding a few lines to tell the head to associate too worked perfectly.

Wires are now bidirectional and working!
