I have a 2011 LS and from my research it used to have a dealer installed option for ambient lighting. I've seen post I'm here before about it. The one for this has been discontinued but is still featured in newer models as well as other gm cars. It's virtually LEDs with a wire hook up featuring a connector. It can be viewed on gm accessory zone under electrical accessories for 2012 and up. My question is where was this particular item supposed to connect to? Because if I can find the stock plug in for this add on I believe I can easily purchase a similar connector and just plug in led lights I can purchase elsewhere for much much less. Again i looking for where gm has reserved for the ambient light hook up to plug in on the 2011 ls.
