    Just getting ready to install my HDS7 Bundle, and wondering if someone can help me out a bit. I have been reading the schematics, but am confused by what to do with the yellow (ground) wire? Never had these on any other units I have installed. Thanks for any help.

    yellow wire is not a ground. It is your “accessory wake up” power. If you have no additional accessories you do not need to use it but it should be capped. When you add accessories all the yellows tie together this makes it so when you power your graph up it will turn your accessories on.

    Connect your power cables to battery/fuse panel for both the

    LSS and HDS. Connect the yellow from the HDS to the LSS and

    the LSS will power on when you power on the HDS.

    The LSS does not have an on/off switch but if you want you

    can use the yellow wire to independently power it (to a switch) or you can tie it to the HDS unit.

    Thank You! Helps a lot. What about the 5 wire Data cable? Can I role that up and store it under the dash?

    Yes you can. I would seal up the ends of the wires though.

    Tape up those little wires so they dont short together and put it anywhere you can hide it

    Last Question, since you guys have been so helpful, Can I tie in all the wires from the same feed (my old unit), or should I have a separate line for each the HDS, GPS, and the structure scan? I think that covers everything

    I would run each separately to the battery or fuse panel.

    Each (+) line should be fused with a 3 amp fuse.

    Thanks Dan. That will not be a problem. You saved me more than a few headaches for sure.

    One last headache saver is to switch the power to your network.

    If you don’t it will drain your battery with its

    constant power draw.

    Let us know if you have other questions/concerns.

    Happy rigging!

    How do I do that?

    If you set up a red NMEA 2000 network you will have to install a power node to power the network. The power
    node should be wired to an available switch. If you don’t
    have an available switch on your boat you will need to
    purchase one.

    Did you set up a NMEA 2000 network to run an auxillary antenna?

    Yes I did. Is this something they are looking to change? this sounds a bit silly to have to put a switch for a GPS antenea.

    I just am thinking there has got to be a better way.

    If you have a fuse panel that has a master power switch then

    you wouldn’t have to add the switch. If you’re wiring direct to 12v then a switch is mandatory.

    You could just remove the in-line fuse after each outing but

    sooner or later you’ll forget and it may cost you some

    time on the water.

    The best way is to switch the power with a lighted switch.
