If You have even a little background knowledge on wiring (Like installing aftermarket LED light), you should be fine. Its really easy as long as you know that difference between the + and - wires, and even if you don't just switch em around HA!
Here's a link to a PDF instruction manual that shows you how to install a EC mirror (Not for Koup) but its all the same. Really its not rocket science!
