Retrofit - Dimming rear view mirror (post face lift)

As the dark nights start to draw in, or more importantly the morning commute in the dark, I'm finding myself dipping the rear view mirror to avoid the numerous following cars with head lights pointing up, left, right, anywhere but straight. Maybe i'm getting old, maybe i'm just starting the journey earlier with tired eyes, maybe its the result of modern, brighter head lights.

I need a fix. That fix is the auto dimming (photochromic) rear view mirror retrofit. This is the first retrofit I've done of a factory option that wasn't pre-wired. There are a number of other threads on this topic, but non where sufficiently detailed to just get on with it, so I'm sharing my learning to help the next modder!

So this is the mirror, you can see the Tyco 8 way GET series connector



Along with the auto dimming function, this mirror also has a humidity sensor/ ambient temperature and glass temperature sensor which connect to the HVAC controller by LIN bus. With these three sensors the HVAC can calculate the dew point of the air and calculate when the screen is likely to mist, and do something about it, hopefully.

I checked the roof harness code on my car (DH52-14335-AFC) which does not include the wiring for the mirror, so I'll need to make a harness. And I have the wiring diagram with the wire lengths on so this shouldn't be too hard.

Well It was pretty easy to find the first connector, and the vehicle side look is populated. Whoop. Its the middle grey connector.

This is where I got stuck as I just could not find the second connector, the important one with the power and reverse light feed! So I went to the best research tool I know, eBay! I found this image which showed me the whole roof harness and the other connector. I'd already found the corrugated tube so could identify where the other tail split off.




So, a short time later I made up the harness with the Tyco connector and some of the pins pre-terminated. I'm connecting the ground to the more accessible roof light ground point.




I'm not sure if I will foam wrap the harness to stop rattling or not. Probably not as I'm pushed for time.

I'll follow up the rest of the installation in the next post.

ive found that having factory spec rear window tints almost negates the need for an auto dimming mirror, my HSE's barely ever dipped as far as I noticed, 2013 FL2 SD4 HSE Auto Orkney Grey - loved it

Hi,

Same for me as RogB my tints mean I have also never noticed my mirror change at all, I am however really interested in your pics and I must thank you as my mirror fell off last winter and the little round sensor thing got damaged. I had no idea what this was and couldn't find out, it didn't seem to change any of the functions so I just forgot about it until I read this feed.

I now need to see if this is something that can be found separately or I can find a mirror with it attached on the old fleebay.

Thank you for a good little how too which I'm sure people will use. If your going through hell, keep going!

If your going to so much trouble to put it in then why not add a USB supply for a dash cam (or something similar)
as I did.

Well, I am rather impressed!

Being an older design the mirror does tend to over dim ( compared to more modern LR products and competitors) and can sometimes be a little slower to clear, but it's certainly fast to react. Didn't have a single misaligned headlight bother me on the way to or from work. Even works with high levels of solar on the rear.

I have pics for a few other useful pointers that I need to upload.

I take your point about the tints. They trouble me though. I spend a huge amount of time in premium SUVs and saloons of all types, and as they all have tints they all feel a bit cave like. I bought DIY tints when I got the car 2 years ago, still in the roll. Been and got a quote from a man, was a fair price. Still no tints. Something I like about the FL2 is how open the cabin is. Would tints ruin that? Does a lack of tints mean the children see more of the world?

DEG5Y,
I already had a USB feed to the mirror for a dash cam. But I agree if some one is going to this length, they should seriously consider running the extra cable.

To save boring anyone with installed condition pictures, I'll post just one more.

This is the location of the second connector which has the pins for the supplied power and the reverse light feed which turns the dimming off immediately when you enter reverse.

I'll update the thread if and when I change the car config to enable the humidity sensor.
