Oh wow that's really good to know. I was at a loss to see what that wire to the brake proportioning valve did because its been unplugged for awhile on my car with no visible effect. Thanks!
Does the wire to the proportioning valve trigger the light once its unplugged? My wiring harness has been damaged by a car fire so what mine does isn't necessarily what it should do. Could he unplug it or alligator clip ground the plug to troubleshoot his light?
I'm guessing the proportioning valve completes a ground to the "brake" light to make it turn on. Thus unplugging it will instantly cut the ground and turn the light off if that's the culprit. True?
