I finally received all the parts needed for the header fan/light hookups. I decided to go for a more "modular" approach. I purchased these www.amazon.com/dp/B00FH6UYLW and these www.amazon.com/dp/B00KWA1RJ6 . I cut the jumper wires in half, and used some of them to connect negative through the switch and positive from the power supply to the pin headers, and spliced others to the fan and light wires, to plug them into the pin headers. This way the only soldering I had to do was wire-to-wire, everything else was "plug & play". I cut up a Command adhesive strip to mount the headers below the RAMPS board. Sorry for the poor lighting in the image.
