They used a few different mirrors. The harness connector is tucked behind the headliner under the left visor (on LHD cars, could be on the right on RHD cars), and if your car doesn't have the IR keyless/alarm system from the factory, it is easy to confuse the harness connector tied up back there for the mirror's connector. If there's any doubt, get a meter and test the leads against ground -- no alarm system in the car means the connector will be dead.
Early cars had auto dipping mirrors -- the harness has 3 wires. Ground, constant power, and headlights on. If you have one of these, wire the mirror up to headlights on/ground, else the mirror will constantly be on and draw current while the car is off.
Later cars ('91-'92) have the adjustable contrast mirror. I don't remember what the harness connector looks like, but it should be standard.
Even later cars ('93-'94, all E32 in the US) use a Gentex 117, which has no outward controls. This mirror uses a standard ~ 6 pin black connector, but again only 3 pins are used.
The last mirror that I know about is the one with the IR sensor built in, which also has an on/off knob I think.
I think you're probably looking at a gentex 117 -- there should be some text to that effect on the windscreen side of the mirror.
