Phone switch lead located.

[attack eagle]

Downloaded the 92 etk and it says it is in pin 10 of x32.
x32 is not in what we laypeople would consider the footwell area (ie kickpanel) it's up in the dash to the left of the pedals...


OBC trigger is yellow/red stripe 10 on x32... still no luck finding the phone lead.
in plain english: ETK is Full of Shi_. it's pointing you to the obc stalk lead, not the phone lead.

SO ignore that!!!

Phone lead is:

:drumroll:

black w/ green stripe, in a single pin connector all by itself, connected to a black with yellow dots wire. up under the dash just to the left of the column, and runs perpendicular to the dash edge..

ETK was dead wrong... I ended up taking apart the column shroud to see what color it was at the switch.





Since I don't need to install a relay yet (to give me two pins to run the bluetooth answer buttons leads to), I simply tapped in the telephone mute lead on the head unit.





without further ado, here are pics so you can see where the connector is, colors, and how nice it is to see "telephone" on the head.
sorry for the fuzzy pics, but the camera doesn't want to focus that close.

This is awesome info. Thanks for posting.

Maybe someone will get to modding a bluetooth before I do.
I just found that the telephone mute will also turn on the amps when activated on my Clarion head, evne if the head was off beforehand, so I maybe able to use all the existing speakers instead of just the second voice coil driver's midbass like the OEM one.

Especially since the primary voicecoil was shot and i forgot I am already running the second VC for the stereo now.

You have a phone button on your dash?

:o

Where's this usually located?

[attack eagle]

It's on the washer stalk, push to activate.
My car was prewired for changer, cell, and alarm.

[Ferret]

I wonder if its some kind of option then... all I've ever seen on the washer stalk is the intensive clean button.

[attack eagle]

you guys didn't have the phone option over there?

[Ferret]

That's usually where the intensive clean button is on 525i's lol.

It probably was fitted if you had the carphone option, which was actually quite rare iirc!

Over here, the carphone option was much more likely to be found on a 7 series. The 5 series is generally considered an "ordinary" sedan/saloon car, rather than a luxury model. The most common 5 series here is a 520i with almost no luxury options; no cruise, no A/C, no intensive wash, the OBC is replaced with an analog clock, and you get cloth manual seats and (on the E28, at least) hand-crank rear windows.

I think my car was prewired for the phone ... I gotta look at that stalk later. lol
