SkiMe, BSM wasn't available on early '13s either. I don't know when Lexus introduced it during the model year. So i's difficult to know if adding it to yours will be a matter of 'plug and play.'

Well, that would add to the complexity wouldn't it!

And it sure looks like the switch is hard to find.....discontinued already, for some reason.

Somebody has to be the guinea pig

The real question is the cost. That usually stops most people

So I'll tip toe into it.....

First item, is there wiring for the BSM switch?!? If there's no plug, that's going to make it pretty hard as a plug n play. So I pulled the panel off and sure enough, there are some blank plugs. Just don't know yet if any of the three unused ones go to a BSM switch. So far, not completely shut down......

you need the repair manual to know which wires are which

I want to add this also to a 2013. Anyone have a factory service manual so that I can take a look at the wiring etc?
