Just noticed that a paper that came with the mirrors containing an authorization code list a part number 23371780. Sorry I can’t tell you about the pins because I had a chance to install them today so I did even though I new I would have to go back in. I’m on vacation too! Not sure why those numbers on the mirrors seem weird ,old stock maybe. I’m pretty sure they aren’t power fold I could move them easily by hand. The mirror glass moves with the power adjust switch but that’s it. Not sure about heat yet. None of the lights work. Let me know what you will need for info that I haven’t included so I can get harnesses. Thanks for your response.
