I have just bought a mirror frame to replace mine, which was cracked. My car is a 1997 facelift 202; the new frame is from a 1999 210. The new frame has a 6-point round plug for the mirror glass. Four pons are actually wired. My old glass has a two-pin connector, like the one shown in this excellent thread: http://www.mbclub.co.uk/forums/electronics/42635-heated-mirror.html Does anyone know which wires I should connect to my 2-pin mirror?
