North Dakota | After thinking about this for a day I wondered about the black box. Is it about 18 inches long and 4 inches square on the ends? If it is that is a NAV 1, one of the very first autopilot systems. Is there a hydraulic steering valve connected to the steering hand pump? It will work with the 150 lightbar and can be engaged with the button on the light bar or you can get a remote pad to put closer to you. | |
