Was the light on before you did the job as well? If so have the OVP (Over voltage relay) tested before you spend money on more sensors.

ABS LIGHT

THE OVP WAS REPLACED AT THE SAME TIME AS THE CABLE TO THE LEFT FRONT WHEEL

Did you take the time to read the output voltage of the alternator?

Light on typically indicates low voltage which is common as the internal regulator begins to fail.

Voltage is one of things that causes ABS light on.

Check resistance at sensors cable connectors to make sure that the wires are OK. Replacing just one is not enough. This one drove me crazy once but solved.
