I have a D100, D120, AP74,SL40 and 327. From the center stack wiring there is a wire labelled GPS TX which contains one white and one white/green. The Lowrance 2000c accessory cable NDC2 has 6 wires of which their box says you use only 4: red, black, white (transmit) and green (receive). Anyone know how they connect?

Thanks
Tim
