Default Wiring for nmea 0183 HELP!

Can anyone help me with wire for nmea0183. I have a icom 602 radio and want to have DSC function. I have 2 plotters on my boat. A Lowrance elite 7 chirp and a Raymarine c90w. Both are capable to use nema0183. I have look at the paper work and have tried to connct the appropriate air combination with no luck. Can anyone help. I have an eprib as back up but it would also be great to have one of the gps plotters talking to the vhf. I leave for NC this weekend and know don't have much time. My boat has been "held hostage" by an horrible boat mechanic (it's a 3 month story for bad lower unit seals)and gave me no time to deal with the wiring.
Many thanks

To connect from your C-classic series will need the yellow-positive and the brown-negative, which are the nmea0183 outputs. Icom doesn't list a color code, but they do list a pin out for that plug. So you will have to figure out the pos and neg nmea0183 inputs, to connect to those wires.

Still not getting gps on your vhf? You will have to go into the menu and settings of the C-series. You will have to confirm the baud rate of the nmea0183 port to be 4800.

also, rm units are sensitive to grounding. make sure your nmea - wires connect to the same neg source as the rm device itself.don't just connect to any neg wire. use the same one.
