I added some layers of electrical tape to stop that action. If those wires rub through, all sorts of electrical gremlins will pop up. Might be worth checking yours.
My 2001 does not have a grommet either. There is a plastic sheath around the wires but adding a grommet would be a good idea. I'll have to see if I can find a large enough one at the auto parts store. I'll have to cut it and super glue it in place.
Thanks for the tip and as you say it would cause all kinds if problems it the wires were worn through and shorted out.
