2003 Oldsmobile Alero Question: ABS Wiring Harness

Ran a diagnostic computer check and founf Code C1233 (RF wheel speed sensor open or shorted). Sounds a lot like a "bad ABS wiring harness". How difficult is it to replace the wiring harness, i.e., how far back to the engine assembly does the wiring harness extend from the RF wheel hub assembly ?? -
