I have a 2011 Nissan versa S sedan with the 1.8L engine and 4 spd auto transmission. I bought the online PDF version of the owners manual with the wiring diagrams and plugs layouts at the BCM. Because the dealer cannot easily add keyless entry to my Versa, I am adding an aftermarket system. However, when I compare the wire colors on my car to those laid out in the wiring diagrams, the colors are different. Are there different wiring patterns for different models of the Versa. Is it possible my Versa is a transition from 2010-2011 or 2011-2012 model years?
