Picture to come later...I didn't actually take any but I can snap a few picture of the interior to give y'all some idea how the entire process goes.

First off, I started the project yesterday with the intention of finishing it up by the time Kaz stopped by to look at his sway/suspension problems. The Mirror and the wiring harness is fairly straight forward, the mirror snaps right off and the harness is a simple plug and play...The instructions tells you exactly where to plug in the little wires into the harness. Removing the headliner is also a piece of cake, remove the long strip on the A pillar, remove the 3 #20 Torx screw, and just yank the cover off. The driver's side Oh Sh*t handle cover hides 2 screws, the vanity mirror has 2 screws, and the vanity mirror holder has 2 screws AND an expanding rivet. Of course, in removing the headliner I accidentally torn my weather stripping, now it's being held in by some epoxy glue. :(

Anyway, hooked up the wiring harness, snaked it along the headliner and clipped them into the existing wiring clip along with some plastic ties, and removed the driver's side vent by removing the trim panel and exposing the 2 screws holding the vent in. Funny side note, you'd be surprised how crappy the worksmanship is in your car. I noticed 1 missing rivet in the passenger side vanity mirror holder and 1 missing screw in the driver's side vent. But I digress. Anyway, I snake the wiring harness around the HPS airbag, through the driver's side vent carefully avoiding the pipes feeding into the vent, and down underneath the driver's side underpanel. All this took about 15-20 minutes, and I was just thinking, god, this is pretty easy! Took off the panel underneath and started looking for ground X217. Checked the diagram, checked underneath the steering column...Nothing. Nothing looks even remotely like ground X217 on the diagram. I even have Kaz look for me and I was baffled as to what to do next...If I can't ground the wires then it might set off some fault code or have some problems. So I just bundled everything back up and drove off since I had to catch Star Wars Episode II in a couple of hours.

Anyway, after playing hockey this morning and a quick shower, my hack instinct tells me it's got to be a lot easier than this. The ground was pretty much the only thing holding up the installation (so I thought). Screw this, I'm just going to find another ground wire and splice in. 20 minutes later I have a make shift splice with one of the provided splitters and found a suitable brown/black wire. Cross my fingers and hooked that up. Snaked the wires around the steering column and up a small, 1" diameter tunnel up to the back of the fuse box. Dismantled the glove compartment by unhooking the hinges, unscrewed the hinge cover, and removed the 5 screws holding the glove compartment in. Voila, dropped the fuse box and found the two remaining wires hanging down from the top of the tunnel. Inserted the blue/yellow wire into the top part of the fuse box (I think this is what provides power when you turn key to access II/Power on mode), inserted the green/yellow wire into fuse position 24 and...Realized I had inserted the wire into the wrong slot. There are 3 slots on a fuse panel, the top one I have no idea what it's for, the bottom one goes to the Central Control Unit and the middle one is where I'm suppose to insert the wire. Great I though, just pull the wire out, right? WRONG. I had to insert a tiny screw driver and pound the wire back out with a hammer because it's got this small tab that holds the wire into the harness/fuse panel. It took me about an hour's worth of struggling to get it out in decent shape.

Now that I got the wire into the right fuse panel, turn on the keys, put my finger over the front censor...VOILA! The mirror slowly dims. Another "successful" hack project completed. I just got to put the glove box back together. :)

Hack, where did you get the dimming mirror?

:dunno:

Did you get the autodimming mirror from BMW, if so what is PN?

Or, did you buy it from the company that makes them?

IIRC, he traded with an E46M3 owner who wanted a non-dimming mirror. I saw HACK's mirror yesterday and its the oval M3 one. Looks cool, and the clownnose is more hidden (which I like) but the overall usable area is smaller. :thumbdwn:

ok hack, now tell me how to DISABLE my factory dimming mirror, since i hate it for the same reason Andy Chi traded his to you: you cant tell when an unmarked cop car is following you at night...hell u can barely see the lightbar on a fully marked cruiser.

it creeps me out when u can just see a pair of dim headlights in your rearview for miles.. :rolleyes:

Great Job! :D :thumb:

Also for those who are thinking of retrofitting the dimming mirror, the E46M3 oval one will work on a sedan too. :) And E46 sedan here ordered it from Germany.
Isn't the oval mirror a bit smaller than the 'normal' ones ?

Remove fuse number 24 in your fuse box inside the glove compartment. Do be aware that also disable your PDC

The oval mirror is larger in surface area but smaller in usable area because of the shape. It doesn't cover the corners in your rear winshield where as the normal mirror will show all 4 corners and then some.

Did your harness come with all the bits noted on the instruction sheet? I got harness 51 16 0 001 231 and received only the harness. The Service manager printed off the instructions from the CD and I notice on page 2 there are about 8 extra pieces I should have. Did you order a different harness number?

I'd have to look it up on my invoice, but it came with everything, including the wire splitters, wire ties, the connector housing, and a spare fuse, and a couple of wire clips.

:D Nice. I always thought the oval one would have more visibility, which is why I thought about getting one (or the lovely broadway mirrors:lmao: ). I would choose for no-dimming, since I hate auto-dimming at night:)
Well, they'll come UN-DIMMING if you don't have autodimming mirror already. The reason why I opted for the retrofit of the wiring harness is PURELY due to curiosity, and the fact that the autodim mirrors does not have that little featuer where you just flip the clown nose and it flips the mirror down. :(

You can always remove fuse #24 too. :)

Yeah, I forgot about that little clown nose:tsk: . But I would never pay the ridiculous amount for the mirror, way too much. Wonder if they have one that is not auto-dim...:dunno: . You were lucky you have a friend to trade with.

Have you been able to track down the part number of your harness/retrofit kit? Or have you been busy working on another mod?!
Sorry, was writing an evaluation article for the local chapter newsletter. :D

Part number on the invoice was 51 16 0 001 231, same as yours. I ordered from Pacific BMW if that matters. Comes with all clips and even a spare fuse.

I just checked and it looks like the oval mirror only comes in autodim.

Just don't hook up the harness and it won't autodim. :D

By the way, bought some REAL rubber sealant/glue this afternoon...The tear in the weather strip is GROWING. :(

But a disconnected non-dimming mirror still costs the same as one that works. :D

I think you need new weatherstrip...
