You should be looking for a white wire for the cold side of the brake switch on your 2000 Chevrolet K2500. I have linked a installation video below of a Tekonsha PowerTrac Electronic Brake Controller # 39523 being installed on a similar 2000 Chevrolet pickup. The technician does mention that at times he has found the correct wire to be yellow, so you will want to test it with a Test Light # PTW2993 to ensure that you have the correct wire.
