abs speed pulses... does anyone know or have information?

So I'm probably pushing smelly stuff uphill with a toothpick but I have to ask at least...

I'm after any information or diagrams people might have in regards to the speed pulses from the individual wheels. I have a little project in mind that needs to count the pulses from the front wheels. Ideally a steering position sensor would be awesome but the 90 doesn't have one.

What kind of info do you need ? Iv got wiring diagrams early and late?
This little project you speak of has my ears pointed forward!

A steering position sensor wont give pulses , what exactly are you after

Any thing and everything. I was working on a 95 today that had stability. The computer for that was labelled abs/trac and located directly above your left foot. If it has stability... then it must have some ability to measure the yaw. Could that sensor be retrofitted I wonder... or is it counting wheel pulses?

No. I figure it will have dual outputs that will vary between 0 and 5 volts.

I've been playing around with arduino and have thought of a practical application for it.


I've live in a particularly hilly area and windy roads. A few months ago I drove a friends car to my place and was so impressed that the headlights turned as I went through corners. I figure it couldn't be too difficult driving lights to do the same. Rotating base is easy enough. They could be pushed by small servos. I f figure if I could the left light to the right and the right light to the left ill be set. But I need to find an input. angle sensor would be perfect but I'm guessing an input balance monitor on the front wheels would have a similar Effect

Yaw sensor is under the center console im fitting this whole system to my car just got brake lines and abs pump now to fit

Where under the centre console? While I haven't looked for one I can't recall seeing anything similar. One fed from the steering wheel directly would be awesome.

My car is a 90... so fancy things like traction isn't available but i do have abs.

Series 2 90s got abs/active trc
Its directly under the armrest bolted to the body but if series 1Body you wont have the mounting points i found this out i overcome that by welding couple of mounts for the sensor to console mount
