| Your main distribution cable should have a flat 5-pin GPS connector on it. If it doesn't, you'll have to replace it with one that does have the connector. (There were two versions - GPS-enabled and non-GPS.)
The main distribution cable is the cable that plugs into the exterior bulkhead connector. It has the connectors for flow sensor input, moisture sensor input, ground speed input, etc...
You can use any GPS unit with the black box yield monitor, as long as the receiver can output data in the following format:
8N1 NMEA 4800 at 1Hz. | |
