ABS Wiring Diagram?Front ABS sensors terminating point drivers side?

[s2dude]

Does anyone have ABS system wiring diagram by any chance please? (S2 3B)

and also....

Front ABS sensors......where is the connector for the drivers side front one in the engine bay?! (is it under the airbox?) //I hope the previous f***wit owner didn't cut the connector !?

Old sensor is missing and I'm fitting a new one. Passenger side one is fine and I can see the connector under the coolant reservoir but also where does it go from here? (out of interest more than a fault!)
It just seems to disappear under that damn battery tray and I am curious to know how they make their way to the main ABS ECU and where they connect to it ....(Im presuming they do?!)

Last off.....where are the ABS relay locations?? fuse 31?
Is it in the main fuse box under the bulkhead?? (if so it seems to be missing )

Cheers

Can anyone help ???

A great start would be to know where the front drivers side ABS sensor plugs into??
Is it under the airbox??

as my sensor is missing (replacing it now)


THANKS

This is the only info I have. Not got wiring info. Sorry.
Pic doesn't explain much either, but may help with finding looking at pipes around it. Can you not push and pull from the wheel arch side so as to see some movement inside the engine bay? That daft 3B airbox might as you say cover it.

I will take the airbox out and see if I can find the little blighter using that pic for a reference......

I did the waggle the wire thing for the other side but the sensor is missing from this side

Thanks.
Does anyone know where the connector leads go FROM the point of these connectors onwards into the car?
How are they wired to the ABS ECU for example?

Do you still need diagrams?
I have the Bently diagrams which covers Coupe Quattro but not specifically S2. I suspect they will be similar. If you PM with email address I will scan and email to you. I am unsure how to post direct to forum but happy to do so if someone can guide me through it.

The wires that attach to the sensors go into the main abs loom that is attached to the pump then through the firewall into the car, some wires going to the ecu, some to the fuse box.
The drivers side sensor should have a plug clipped onto the turret/flitch. On an aby you dont have to remove the airbox to disconnect it. I'm breaking a 90 quattro 1991 year and I think the set up should be the same
