2 Low Input to 2 Higher Output Relay Board

I did up a quick diagram of the little PCB board I made with some great help from Andrea lannaccone from Face Book. There are smaller ways to do this but this is pretty small too, you can do this type of switching with a Transistor too. For what I am doing with my Top Countdown Indicator lights to activate the switch lights on my Lower Console I only need one side of the board but there was room on the board to have the same ability twice so at least I have an extra setup for should I need to do something similar again. :) 

PCB Board Installed

I installed the small PCB board later today just overtop of the other Relays board I had made a few weeks ago. I have the power wire (blue) going from the fuse panel I installed under the passenger side Hush panel into the magnetic coil and switch terminal of one of the mini Songo 12V 10 Amp Relays, this will supply power to energize the coil and provide power to one side of the Relay switch. The other blue wire you can see coming out of the top of the Relay is the 2nd power wire on the other Relay switch terminal, this wire goes into my Lower Console to supply power to the switch lights. The Relays switch will connect the two completing the circuit. The two input wires Red and Black that connect to the Optocoupler I have going into a couple of spare sockets I had available on my Molex connector for my LCD and GPS screens. Those will provide the low input signal to activate the Optocoupler once the Countdown indicator reaches it's last light, this will in turn activate the Relay making the connection as described before. Tomorrow will be the big day I test this out so if all goes well I'll be doing a video to demonstrate the final effect.
