ECU Speed Output

[T.Trophy]

I'm looking at enabling my boost per gear on the Clio. I have a sensor mounted on the rear NS ABS ring but I'm not 100% sure its going to work, I recently found the spec sheet for it and it says the teeth need a min 10mm spacing which the ABS ring doesn't have.
I figured I would explore the OE speed outputs, obviously with it being a 182 it runs out of the ABS unit, does anyone have the correct diagram and any idea what sort of output it gives?

Thanks

Steve
