Thanks for image of radio connector with info on pins for mics. I have exhausted myself looking for which wire set 29/30 or 39/40 is for the drivers side mic in headliner of my 2017 Ram. If you have that knowledge and will share you'll save an old man much grief, I haven't gotten to the point of pulling headliner but I'm near it. Taking advantage of down time due to spine surgery to install Kenwood DNX893s, that I bought 6 months ago, and want to splice mic terminal into factory mic to avoid gaudy looking mic provided with radio, not a good place for a stick-up! Any tips members may have as I'm still waiting a couple of more days for adapters to use factory SiriusXM antenna and to plug console aux outlet into Radio or questions about install I'll gladly share. Blessings, Robert
