I'm posting the same thing again because I didn't get any answers last time so; Does anyone know how to wire M3 Power Mirror? I bought them from eBay but they didn't come with any instructions, on top of that my stock mirrors only have 3 wires and the M3 ones have 4 brown,black,white,blue, I tried to install them myself but the fuse keeps getting burned so any instructions would really help, by the way my car is a 93 Civic LX 4 Door

ok ive never heard of having 4 wires before. do your m3 mirrors have leds in them??? Heres how i wired mine. I took a 9v battery and found the wire combos for wut does wut like on mine green and yellow was up and green and black was right. Then i matched those to what the wires in my car did. Also theres only like 12 combinations or something so its not too bad.
