Routing the wire and the final hookup
The three horsemen are animated by the sequencer. It is the larger box on the left. The fourth horseman declined to take part in our project. This particular sequencer has three leads to which each el-wire horse is attached. Might want to go revisit the wire prep
section again. The letters are connected to a second inverter. It's the smaller box on the right. Now, if your sign uses multiple inverters and/or sequencers, you can hack them to use a single on/off switch. I ran out of time, so there is a switch on each box.
Notice that there is a lot of extra wire looped around back there. Feel free to trim any excess wire from your sign, but make sure to leave enough that you won't have any problems connecting to the inverter(s). I used velcro strips and dabs of hot glue to keep things in place. Attach a wire hanger and you're finished. To add a little protection to the exposed wires I draped a black cloth over the back and tacked it into place with hot glue.
