Ok, I ordered the new mirrors back in October and they arrived and were beat up, broken and used (they had bug splats all over them) and I eventually got my money back but they didn’t want them returned. I was just cleaning out the garage and was going to g to put them in he pole barn to save...
I did it on my Mustang and yes you have to change settings in forescan to make it work. I had to get harness plugs and wire stuff into the can bus. It’s tricky but doable.
