Pin 1 is the true ground speed (radar/GPS) signal from the tractor 7-pin Amphenol connector. Normally this would connect directly to the green signal wire in the 4-pin AMP connector on the CT350 (weatherpak connector is not stock). If either red or black is connected to pin 1, you should be in business.
