-Two pieces of Wire
-Screwdriver (If you have an adjustable voltage regulator
-Block Terminal Connector
-12 Volt DC Power Adapter (I have one here which does 1.5 Amps, from an old wireless router)
Step 1: Decide Which Wire Is Which
Then you can start stripping your wires, strip the 4 wires form the molex plug, and then strip 2 pieces of wires on both sides so that you can use it to connect the power supply to the voltage regulator.
Step 2: Tinning the Wires
Step 3: Soldering Wires Onto the Regulator
Once the input wires have been soldered onto the regulator, you can then solder on the molex plug on the output side. Be sure to connect the RED and one of the black wires to the voltage regulator. Using the same procedure, solder the RED wire onto the +Output of the voltage regulator and a black wire onto the -Output of the regulator.
Step 4: Connecting Everything Up
BE SURE TO CONNECT THE YELLOW WIRE TO THE WIRE COMING OFF OF THE POSITIVE INPUT SIDE OF THE VOLTAGE REGULATOR AND THE BLACK TO THE NEGATIVE INPUT!!!
I have simply twisted the wires together as the will be going into a block terminal connector, there was no need to solder.
So the YELLOW wire goes straight to the molex plug, and so does 1 BLACK wire, then the signal goes to the voltage regulator, where it is regulated to 5 V DC, and then the RED wire comes off of that and so does the other BLACK
Step 5: Setting the Voltage Regulator
Step 6: Enjoy!
Be sure to insulate the voltage regulator and wires, or make sure that they don't come into contact with each other causing a short.
