I'm assuming I can do the reverse of what you did and swipe the rear fog LED and control chip and solder it onto my own?
Absolutely! That is why I included that last photo showing where the rear fog LED and chip are. Be gentle with the soldering iron and you should be golden.
Oh and the polarity of the LED is important. Just be sure to get the components oriented correctly when you transfer them
