Need help wiring a power mirror . . . .
 

My 240D only came with a drivers side rear view mirror. So I went out and looked and found a power passenger side mirror as well as a power mirror switch and connector on E-bay. I'm by no means knowledgable in wiring things together, but figured how hard could this be. I figured I could just connect the same colored wires from the switch to the mirror and then find a power source & ground. No such luck! :( The power mirror has 3 wires Grey, White & Black. The switch has 2 brown wires, black, white, ( I was doing this from memory and forgot the other 2 wire colors) anyhow, I assume 2 of the wires go to power & ground (looks like brown & black). That leaves 4 wires to connect to 3 wires . . . Arrrrrrrg!
From my poor description, can anyone help? If someone knows how these wires should connect together, please share the knowledge.

Check out this site, http://mb.braingears.com/. You should be able to find a wiring diagram there. Look under the W123 300D turbo model.

I tried the web site and the 240D and 300D years that I tried all ended up not able to display . . .

If someone knows what color wires connect to what, that would be great!

Progress so far . . .
 

Here is what I have done so far. I used an old 12V power supply and played random wire splicing until it seems to work. :confused: I'm not sure if it is correct!

The connector for the switch has the following configuration:
pin# --- color of wire
1 ------ 2 brown
2 ------ green
3 ------ empty
4 ------ red
5 ------ black
6 ------ white

Here's what seemd to work as far as wire splicing:
Mirror ------ Switch
Grey ------ Green
White ------ Red & Brown
Black ------ White

Switch To Power Source
Black (+) and Brown (-)

Has anyone else done this?

Took a look at a 1984 schematic. Switch wire #1 (brown/green) goes to mirror #2. Switch wire #2 (brown) goes to ground. Switch #3 is not used. Switch #4 (white) goes to mirror #3 (white). Switch #5 (green) goes to mirror #1. And switch #6 (black/green) goes to fues #4, which is hot in accesory, run, and start. Mirror terminal #1 looks to be the common wire for the two mirror motors.

KCM, thanks for your time on this. I was reading another post this morning and found out why the website would not work for me. I was using FireFox for my web browser and it will not open the pages :rolleyes: . I currently have IE :( running in another window and am trying to open the pages now.

I really do appreciate your assistance!!! Once I get the site open, I don't know if I could make sense of the wiring diagram or not.

Thanks again for your help! :)
