speed sensor

Hi everyone, I'm new to the forum and hoping for some advice please. I have recently tried to resolve what I thought to be a classic ABS/ESC rear right wheel speed sensor fault by replacing the sensor with a compatible (I think?) RIDEX Plus component...

I received a number of warning lights including: Stability Control - ABS - TPMS - Front Assist - ACC Scan showed the following; Address 03: ABS Brakes (J104) Labels: 7E0-907-37x-MK100ESC.clb Part No SW: 7E0 907 379 Q HW: 7E0 907 379 N Component: ESC H06 0133...

So all of a sudden my T6.1 converted van has developed an ABS fault, the rear right speed sensor shows as short circuit. I have taken it to VW but as its converted they don't want to touch it as they suspect the converters have drilled through a cable loom somewhere. What I would like to know...

Could any of you guys help me with the location of the B464 that contains the speed sensor wire , need to splice into it , many thanks Steve
