Did they mean ABS sensor harness?  If they said the wiring is bad, yes this would cause the problem.  If there is nothing else wrong, that is the only solution.

Please clarify if they meant the sensor or the harness.

The lights should go off when you start your car????? If the lights stay on, then there is a problem! I guess I am not understanding the problem????

I think he means go off as in they come on.

the warning light for the abs stays on constantly. and the light for the traction control stay on constantly. meaning i have no abs and traction control.  dealer said it is the sensory harness. never specified.  but they said it would b about 250.00. and i cant afford that

Have you actually taken it in to get a diagnostic on it yet? If not do it and the computer will log all the errors and then you'll have a way better idea.Sometimes it's a problem with a dirty sensor on your braking system that sets these off,and you can clean it.Have you tried spinning the tires to see if the ta light goes off and back on again? If it is the harness then you can find a used one but I think it's be better to spend the 250.00 for a brand new one that is warrantied.Let us know what you find out so us other GP people have an idea in case anything like that should happen to us.
Good Luck!!

Your wheel bearing and sensor ring is all one piece. Easy to change. Most likely the problem since they did not give specifics and the cost the quoted you. Will need to know which wheel is tripping the light. Only a good auto service center would be able to access it. Hope that helps.

It could be a number of things. It must be scanned first. I have the same problem. Once scanned, it was found the ABS/TC module is shot. This is an $1100.00 item plus labour. I'm installing a used one instead. $50.00.

ya awhile ago they said a bearing was going bad with my front drivers side. thats probly it   thanx mike  i will get that fixed and let ya know
