Fcv800 color matching NMEA 0183 to GP1871

So I have my GP1871f connected to my FCV800 via NMEA0183. And I think I did it correct. Blue wire TD to blue RD white wire TD to white RD. (Or is my wiring wrong ? When I push the Mark key is keeps saying no position data. Does anyone know what color wires go to what color?
 
No worries.Let me know how it goes.
Worked out perfect! At first I had the boat inside my garage which made it not receive satalite connection. And when ever I pushed mark it would show up as no date on the fcv800. The moment I move the boat outside the garage the 1871 satalite came on. And the FCV800 started marking. But those darn wires are so thin. I ended up soldering everything together and than electrical taped it all.
