F60 Auto Dim Homelink mirror retrofit
 

Hi, New Mini F60 owner. I bought it with the standard mirror and want to add the auto dim Homelink mirror. I was able to find the mirror and have everything I need to physically install it but I'm not sure on the wiring and I don't want to damage the mirror. The mirror has 4 wires like this:
3 - Red
6 - White / Black stripe
9 - Blue
10 - Brown

I'm sure the brown wire is ground but I am unable to find any detail on the other wires. Every wiring diagram I can find is different. I can find the same connector (X-18246) but all pinouts are different with either more wires or in completely different pin placements.
Does anyone have detail on what wires should be connected to what? My thought is I should have one constant hot +12 and one switched +12. But I don't know which wire would be which and then I don't know what the 4th wire would be used for.

Any help would be greatly appreciated.

Thanks!

This is what I’m using for my 18 f56
 

Thanks 6FT6!!!
Looks like the pins match (3,6,9,10) but not the colors. Well, 3 and 10 do, but not 6 and 9.
I do have rain sensing wipers. So you are saying to match the brown/blue wire from my rain sensor wire to the blue pin 9 on the mirror? Then what of the last pin that looks like it's for the alarm? Just leave it disconnected? Makes sense as I don't have an alarm but I want to verify with you.

To verify:
Mirror pins
3 - red = +12v constant power or switched power?
6 - white / black stripe = no connection
9 - blue = connect to rain sensor brown / blue wire
10 - brown = ground

Does that look right?
Thanks again!

On my mirror the 6 and 9 colors are reversed from what you said. I understand what you are saying but based on the original pdf diagram you showed it looks like I should follow the pins and not worry about the colors. The diagram itself shows violet and gray as the colors. Here is a picture of my mirror pins.

I did order the mirror plug, or what I think is the mirror plug as it hasn't come in yet. I ordered this: https://www.ecstuning.com/b-genuine-...t/61120140175/
From what I can tell this looks like the right connector and it's the only one I could find. It only has 3 wires but I have other wires and connectors I think I can use. I'll let you know when it comes in if it is the right one.

And thank you for the wiring diagram. I couldn't find the right one. If you don't mind, where did you get that diagram? I'm always looking for additional web resources.

The connector came today and yes, it fits perfectly! Hopefully I can get this done this weekend. :)

Thank you for all your help!!!

The folding mirrors are something I'd like to do too. I saw they used to make a retrofit kit but can't find one for this generation. Please let me know what you find.

Thanks for the schematic info. It's funny I looked there but have trouble navigating the menus - not everything makes sense as to where it's located. Or maybe it's just me. :)

I want to get the alarm added so for now I think I'll leave the alarm wire coiled up under the headliner. Does your Mini already have the alarm or did you add that too? If you added the alarm let me know if you have any pointers.

Thanks again!

Thanks for the search idea. Funny, I had always tried to navigate the menus which was a bad idea.

I was able to complete adding the mirror over the weekend. It works fine for the compass, garage door opener, and the auto dim function. I had some wires from an old Audi harness laying around and added the needed wires. I actually added a red and violet wire like the wiring diagram since I was connecting with a shorter wire anyway. I connected to the three wires from the rain sensor which was right above the front light cluster. I then connected the 9 wire to the A21*1B using another Audi wire. Overall it went really well.

The only questions I now have are around the way the car keeps the ignition light and compass on for a long time. I never checked this before adding the mirror so I'm not sure if this is normal or not. When I leave the car unlocked, like it is in my garage I see that the compass and the ignition switch light stay on for a long time - more than 5 minutes. I have not timed it yet so I don't know the exact time. I made sure my key was not near the car and kept checking it. After a long while I looked and all lights were finally off. As soon as I open any door the compass and lights come back on and the garage door opener works even with the car off. This doesn't seem right to me but I could be wrong. Finally I rolled the drivers window down and waited long enough for the lights to all be off - I then reached in through the open window and tried the garage door openers. Nothing happened which I expected. However, as soon as I opened a door everything came back on including the garage door opener.

At this point I'm going to leave it as it seems like it's working correctly with everything else. My only thought is that I should've used a different power connection or maybe I need to make a change with coding which I haven't done. Do you know if there is coding needed when you add the mirror?

I'll post some pictures soon. Thanks for all your help!

No coding required, you have simply connected to a delayed off power supply instead of an ignition off source. 15 minutes I think. I would not bother about it.

Maybe on my next project I'll run the wire to an ignition source but for right now I agree it's not anything to worry about.

Thanks!

Funny, I used the exact same wire connector that 6FT6 posted.

Could the reason for the compass staying on be for those that use the auto start and stop feature? If you had the car in that mode wouldn't the compass be turning on and off with the engine if you used fuse #52?
