Near Intersection of I-35 & I-90 Southern Mn. | Pins 2,3 & 5 are the pins used for GPS universally.
Pin 5 is always signal ground. Pins 2 & 3 can get confusing because of the null modem situation and connector sex. Pins 2 & 3 are transmit and receive. Transmit from the GPS standpoint is Receive from the Ag Leader's standpoint so this adds to the confusion.
You really only need two wires maybe only one. I really haven't told you much other than it can be done and can be confusing.
Just be sure you don't have anything connected to Pins 4 & Pin 6 of the Ag Leader as they are power and ground OUT which you do not need nor want in this case as they could cause damage. These pins are very handy in other situations but not yours since the GPS system is alive already and doesn't need power or ground to live on.
