Hi, I have bought a second hand gen Toyota auto dimming rear view mirror to install in my 2013 Auris hybrid that did not come with one. New mirror has five pin white plastic connector, my car does not have the opposite side to connect to? Assume if I find out which two pins are Earth and feed I can connect a fused supply to these?  has anybody done? Have a wiring diagram ? The connector ? Any help much appreciated, Thanks in advance
