Hi

My 2011 LF55 occasionally brings up an ABS warning. Have plugged it in and checked for faults, it's coming up with 3-10 wheel speed sensor driven axle left frequency signal.

We've got a sensor to fit when we pull the hub off, but my mobile mechanic thinks it's more the flylead. Have fitted new lead to NSR but warning on all the time now. DAF wiring diagram showing wires 4628 and 4629 at connector at bulkhead. Connected the fly lead there. Original wiring is black and grey but the new Wabco lead is black and brown. Connected both blacks together and the grey and brown together. I'm assuming that's correct?

Cheers for any help.
