rear right WSS harness

[dz09x]

been having issues with Trac and ABS lights for a while now. Traced it back to the right rear wheel. Replaced the whole hub(bearing was bad) and the light still comes up and code reads the same hub. So i looked at the male connector and noticed the pins look a little rusty. Tried some conductive grease. Worked for a few weeks and the light came back. This time it only comes back on hard bumps.

My question is the harness easily replaceable? If i recall the front harness for the wss is a part of the engine harness. Does that mean that the rear abs harness connected to the body harness as one unit or is there a connector somewhere where i can just buy a new harness and just plug it in. I know the last option is getting just the connector and splicing it in. Would like to avoid that if it is possible to just plug in a new one.

as always. thanks for the help.
