Between a couple different forum topics on this, I wanted to consolidate down what I did to help others out.
A couple links to start you out.

Zip ties (As necessary)
Tools
Hand Deburring Tool
Crimping tool for JST Connectors and Molex Connectors
Heat gun
Process
1. Fan Sizing. With the machine off, measure the diameter of the coil you will be putting the cooling kit on. Use this diameter to determine the radial heat sink size closest to the one required for your machine (most fans that I have received have female connectors).
2. Thermal adhesive. Apply the thermal adhesive to the inside of the radial heat sink overlapping on the outside edge to slightly covering the side of the fan. Keep on the blue protective film until ready to install on the coils.
3. JST Splitter. Choose the correct JST Splitter for the number of coils you want to cool (Note: some fans switch the male and female connectors). Cut off the single female side and connect it to the 18 AWG red/black wire. Black to black and red to red. Using solder seal wire connectors and heat shrink tubing connect the 8 ft cable (This cable will need to be long enough to get from the lower flippers to the power supply). On the other end crimp the 5V red wire and the ground black wire. This will go into the standard .093 Mod Molex Connector 5V red wire in the middle and black wire in the point end. (See Pinballlife mod power supply linked above for the positions).
4. If you bought the pinball life mod power supply then just plug directly into that. If you want to tap off of 12V power from somewhere else then you will need to use a 12V to 5V 3A 15W Buck Converter Regulator Step Down.
Happy Modding!
