I've done a lot of search and reading and I keep getting more confused. I recently acquired a 2017 2500HD with the Duramax and the exhaust brake. It came with the little DL8 mirrors. I wanted towing mirrors. So I learned the hard way about the ambient temp sensor. I've sense taken the aftermarket mirrors back off to turn the check engine light off, but on the quest to put them back on. I've ordered a kit from BoostAutoParts that will give me the ambient temp sensor, way over priced for what it is, but it will just allow me to plug the sensor into the aftermarket mirror plug. Anyway, now for the question, I want to get the other functions (Turn signal, Park Lamp, cargo lamp) to work too since they didn't work when I originally had the mirrors on. I've seen a lot of part numbers, but that is what has me confused. I think I've either narrowed it down to one of two sets of wiring harnesses. Left Right 84290984 84290964 84125571 84125561 Which of these sets do I need or is there another set I need?
