I bought a 2009 dodge ram laramie 1500 with the trailer package. Dodge is telling me that I may or may not have the connector to just plug and play a controller in it. Where do you look for the connector? (right side left side ), I know under dash. If you look at 2010 placement of it it looks simple. Also if not does and I need to buy the connector and controller is it a simple hook up? and what are the colors to put the connector to?
