For a couple weeks my wifes Monte Carlo has had an ABS light with a Service Traction Control and Stabilitrak warning light/message and forgot to mention it..

We were under the car checking the oil and found that her ABS wires were severed and just hanging loose behind the passenger side front wheel.

I wasn't able to see much while under the car as it was getting dark, do I have to remove the rotor and hub assembly to get the wire harness? Does it plug into the hub on the outside or do I have to take it all apart to fix it?
