Idiot Lights Everywhere!!!!

My ABS light came on and so did my Traction control light but it turned out to be only a loose wire on the ABS harness my brother had a left over wire clip so he cut out the bad wire swapped the new clip in and now the lights don't come on at all

My hub went (lots of grinding noise) but after i changed it the ABS/ Traction light was still on. So my guess is that it's the other side. Hey Wayfastwhittie where is the harness located? Maybe this is my problem. In the summer it was on all the time but now that its cold and snowing the light is off when i start the car and after about 5 seconds of driving the light's come on.
