Hey, Sorry I didn’t give you better information first hand. I bought a set of aftermarket “DEDC” mirrors on amazon, they were supposed to have power mirror adjust, turn signal in glass, heated glass, running light, and the little reverse/clearance lights on the back side of them. As far as I know, they weren’t equipped with power fold/extend or puddle lights. Possibly part of my issue? Anyways, I did not touch my factory DL3 door harnesses, I thought the towing mirrors that I ordered would be a plug and play upgrade. So I went ahead and made the extra hole in my door for the fourth stud (*doh*), and installed the mirrors. they plugged right in and I went ahead and hooked everything back up, put the door panels back on, go to test my install and the only thing I notice that works is the power adjust on the glass. No lights. Anytime I used the turn signal (left or right), both front turn signals flashed. Not in sequence or anything, the front of the truck looked like I had my four way flashers on. The rear turn signals still functioned properly though. I just put the dl3 mirrors back in and have been driving around pulling my camper with clip on mirrors ... and after much thought I’ve decided I just can’t do it anymore I really would like the extendable towing mirrors!!! Bottom line, I can live without power fold even if it means having a useless button, but I would like to have the towing mirrors, doesn’t have to be OEM though. Not really interested in having $1200 sank into a set of mirrors if you know what I mean. Are there any reputable aftermarket suppliers that you would recommend? Thanks again Phil!
