I know from what i have read that the are controlled together.....but by what? I have already scoured the threads and have seen people with similar symptoms but no solutions....help please! also no CEL on the dash either....

i pulled the positive terminal off and that did not work....doest it really matter positive or negative just as long as one is not connected?

Already did. No luck......when I test voltage across the connector at the 3rd brake light with the brakes on I am seeing around 6volts....bad ground maybe? Or is the switching done on the grounded side
