LF Clean Speed Signal

Post by Sephanite » Wed Jul 02, 2008 10:45 am

I am looking for a place to connect a clean speed signal. Normally, it is connected to the abs or brake (?) but the z4 has a lot of noise in these sections. Any other sections?

I'm working on figuring out the Power Folding Mirror retrofit, and found that Pin 8 of the DSC has a speed signal which connects to the mirror module. Other people who have done the retrofit have grabbed the speed signal from the instrument cluster as stated above.

I also would've thought there would be a speed signal for the stereo as it has the automatic volume/speed sensitivity function - the diagram I have for X18126/X13646 lists pin 10 as 'phone mute (speed signal)' but I have no idea if that is a clean speed signal or not
