[QUOTE="Chiefblueman, post: 1141330, member: 29249"] AVCC purple wire does indeed put out a small amount of voltage/current, as measured by my vom. 4 or 5 volts IIRC. Without voltage, the unit cannot detect ground. Unit needs to see ground to allow engagement. This weak voltage is brought to zero when grounded. Connected to the brake light filaments, the purple wire "sees" ground through the filaments which are grounded. If both brake light bulbs burn out, path to ground is lost, the voltage from the cc unit floats up, showing the unit has no ground on the purple wire. Unit shouldn't engage. [/QUOTE]
