GR86 GR86 - Auto dimming interior mirror install

[AndyRC]

Someone in the US has done a very useful “How To” on installing an auto dimming interior mirror on the 6T , no idea if it will be the same for the 6MT.

Toyota Dimming Mirror PT374-18220 Install on GR86 6AT...

Here is an install of the Toyota dimming mirror, part number PT374-18220, on a GR86 6AT with Eyesight camera system with some tips. You will need a Torx 20 and 8mm socket. You can disconnect the car battery as well, but the harness is only active with ignition on, so if you are careful and...

The website - https://www.toyota.co.uk/new-cars/gr86/features-and-specs is still showing "Electrochromatic auto-dimming rear view mirror" so in theory we shouldn't have to worry about having to do this, but, the original equipment list showed rear parking sensors, and the demo car seen at the MR2 event had a standard, flip to dim, rear view mirror, so it's anyone's guess.

it's anyone's guess.

All part of the fun when slapping down a deposit on a car that hasn't been reviewed and you haven't seen, haven't sat in, haven't driven... and arrives in a fortnight:

Shame they've ditched the frameless interior mirror from the previous generation. Always thought it was a nice touch (although it did have common issues with delaminating).

I've ordered one from the US on ebay so assuming they post it I'll update the thread and let you know if it works on my manual car. £220 posted.

Ok, 5 mins with a screwdriver and trim tool would have saved me £220, but I don't have the loose connector referred to as RF44 in the GR86.org thread which is required for the small 3 pin mirror adapter. At best I've now got a slightly bigger mirror (its not here yet but delivery due today as I'm writing this)

I may see if my local car electronics car people can get power to it, must be a way.

Mines a manual, but I dont think that's why. Its just an EU car thing I think. Took a pdf link from that GR86 org thread which shows manual and auto cars have the same spare wire fwiw.

Shame, but if all it needs is power, then perhaps you can just run a cable behind the leading edge of the headlining, down the A-pillar, then tuck it into the trim to get behind the glovebox, and I think there's the fusebox there. Then you could just use one of those fuse tap thingymajigs to plug it into any slot which provides power on ignition and Bob is your mother's brother.

Thanks

The fuse tap piggy back things?

Will look into that, ill likely have to cut and extend the wire adapter.

Electrics aren't my thing really

Yeah....think you need micro ones, like this sort of thing: https://cpc.farnell.com/multicomp-p...3292&s_kwcid=AL!5616!3!490819648758!!!network

And I'm with you..... don't mind having a crack at oily bits, but electrics may as well be dark magic.

 

[Bathroom_Security]

Looks good. Will try this fuse piggy back thing

 

[Bathroom_Security]

OK, wired it off the radio fuse with a piggy back. Earth to the bolt which connects the fuse bank/box to the mount its bolted to.

Ran the wires up the a pillar and behind the headliner and then between the headliner and the plastic mount for the roof lights, same way the RF44 connector in the photos does. but I'll need to figure how to keep them in place as they come forward.

I butchered the adapter that came with the mirror (the one seen in the install guides) and took the white and black wires, stripped the ends and connected them to the plastic lever nut wire connectors which you can see dangling in the photos.

It works

Thanks conscript!

Glad it worked. Not sure I'm ready to drop that sort of wedge on one myself. Maybe I'll leave it as a little mod to do at some point.

@Bathroom_Security Can you add the link to the eBay page that you got the mirror from?

If it'll fit a toyota windscreen mount I'm sure you can get any dimming mirror and power it off the fuse box like you would a dash cam.

The toyota one does seem very nice indeed, works very well.

So I took the plunge and ordered an auto-dimming mirror from Octoyotaparts. Took about 10 days and arrived today . Now need to fit it.. weekend job.

 

[sim61]

I got the auto-dimming mirror fitted and working today. Also got the HomeLink (which is on the mirror as well) working, but try as I might, the electric garage door won't go up and down. I don't have instructions for the door so am being extra cautious as I don't want to unprogram the two remotes that do work! More research needed.. or get someone in to do it for me.

Having other cars with auto dip RVMs, I'm glad the GR86 is manual so I can decide when I'm getting blinded and not some sensor getting it wrong... slowly ..


We've got a little box on our garage doors that's linked to an app on our phones. If I'm on Android Auto I can speak to the car to open the door. Not that I do 'cause I feel a berk talking to a car*.

*And I forget the option is there.
