So I think I've ended up with a set of these mirrors but now have no way of re-activating it witout actually getting the vibration ecu :(

COMPUTER,ASSY MIRROR VIBLATION CONTROL 89140‑20050

Thing is, in the EPC the some cars are listed as having Ultra Sonic Mirrors

"87940‑2B490‑A0 アリ(デンドウ カトウシキ ULTRA SONIC MIRROR)"

Noting that I hooked the two leads to this mystery device up to my stereo and surely enough... music from my mirrors :shock:

I'm going to try and source a "viblation control" unit to see if it causes the mirrors to "viblate" like others have described but to be honest I have no clue where to go looking for it...

I can post pictures of the 'speaker' if anyone is really interested in seeing it.

it should just be a basic oscillator, I can;t see that circuit being very complicated.

Did some reading and from what I gather on other Toyota forums this was advertised as Ultra Sonic Mirrors to blast off dew when the mirror was wet then you could turn on the heater and get rid of the rest of it. It is piezo based so me blasting my tunes through it isn't far off from accurate. Sounds as though the speaker is happiest at about 14khz so the ECU probably just blasts a few clicks around this range in rapid succession and the water should dance off.

I think what I might do for now until I get the control unit is just wire them into the door tweeters XD

If you've got the controller box I mentioned previously maybe you could open it up and take some pictures of the schematic for us and we can help figure out how to wire it up.

You might have to ship the box to me and I could figure out the circuit diagram and how it gets wired up for you. Depending on how complex it is that may be the only way.

I assume that the only way to make the system work you need the computer box with 89140‑20050 as the part number on it.

The one you have says 87989-17020 which is the part number for the MR2 power folding mirrors, not the Celica 87989-20030 one... :shrug:

I'd buy that switch for the vibration from you seeing as you can't use it with what you have...

So what does this vibration control thing look like? Since I cant find anything when I Google for that part number etc.

Actually this was a set, and that relay came with it. So im guessing its interchangeable. They seem to be very similiar.

But I want to hook this up correctly. And how do I know I have vibration mirrors? The heater button is also the vibration button from what I have gathered.

The vibration control box looks very much like the folding control box.

And how do I know I have vibration mirrors?

The power folding mirrors will have a 7-pin connector. The vibrating mirrors will have an additional connector for vibration.

Doesnt the heater have additional as well?

Any wiring diagram on the heater button? And it doesnt look easy to find that vibration control box.

The vibration box is about $500 new from Toyota if you really want it.

The mirror heaters are run off the same circuit as the rear glass defogger not the vibration circuit.

Only way to be 100% sure you have the vibrating mirrors is by taking off the glass and inspecting the setup internally.

Well theres no doubt after opening the mirror, its supersonic. Speaker/vibrator mounted behind on the mirror etc.

This makes the replacement mirrors I ordered useless though... or can you move the speaker? Wish there was a guide.

I need to get that vibration control box it seems. Waiting for wiring diagram from Toyota Japan.
Toyota doesnt make it anymore btw. Plus it was priced around 350$ new.

This sounds right from what ive read also. Does this mean you have vibration as well?
I would love to know how its wired up.

I wasn't saying that the button doesn't heat the mirrors, I was saying that the rear defroster is a high amp circuit where the mirrors draw current from to heat up.
