I have a set of AC Schnitzer mirrors I've been waiting to install for the longest time. Before sending them off to the shop to paint I wanted to make sure they work properly. If not I was thinking of getting some m5 replica mirrors w/ OEM connecter for easy install. Well today I removed my stock mirrors and tried to see how the wiring goes but they were not visible and inside some black tube housing? I did not want to cut open the tubing, etc... w/out know what I am getting into. How difficult is it to wire the new mirrors in and how do I do it. The ACS mirrors have I believe 3 cut wires hanging out? I have to go back and check the color. I would prefer to do a clean install if possible. I thinking I'm going to have to cut throught the tubing and strip the old wires and just connect them? Any help would be great.
