Fig. 3-13: Wires installed in the RAMBo power connector.
I made Fig. 3-13 pretty big so you can see exactly how it is supposed to be wired up.
Once you have the connector installed, grab a couple of the wire ties (or lacing cord!) and bind
up the black & yellow wires that go to the connector. It's not strictly required, but it makes for a neat
appearance. You can do the same with the black and green wires that will eventually be connected to
the power switch. (If you're gonna brag about your baby, she's gotta look nice!)
