Step 5 : The addition of I/O exterior barrier strips, Status and Power indicators, and a Switch
I decided to use the extra half of the relay for I/O circuits on barrier strips, for in this particular case, the control of fog machines, or for those of you with those christmas lights with a button to change power, there you go. These strips do open and close with the corresponding outlet.
Here it is midway though the barrier strip and indicator insertion:
And here is something to bleed out of your ears if trying to imitate(much easier if you are to take it step by step).

Step 6 : Mounting the Kit 74
Not very exciting, just ran the wires of the binding posts from the relays and attatched it to a "wall-wart(not seen in thgat picture, but the wall transformers, I opened it up and used the transformer)"

Step 7 : The most complicated hinge in the world
Now at this point I could have easily just attatched the relays to the kit 74, but OCD made me decide to put a 25 pole relay at the edge of the box and the door. I attatched the 16 leads from the seperate LEDs on the door to this strip. I then ran a hot from each relay to the strip, and joined all the nuetrals together for each relay and ran it through one common. I set up a corresponding strip on the bottom which attatched to the kit 74.
I then joined the two

Step 8 : Explanation of the kit 74 connections
The kit 74 already has 8 5 amp 3 pole relays on it. But I figured I'd get some heavy duty ones, with 6 poles, which would both allow for more current to be drawn(well, not really, i dont have any 40 amp plugs in my house I am aware of, besides the dryer maybe, but thats 220volts, and thats a whole other thing)
Anyway, I used the kit 74 relays to switch on and off 120 volts to control the other bigger relays.
