Wiring two df to the same cable

I've got a 570 di and a 385 ci and about to upgrade to a si on the helm so wanting to put the 385 up front to have gps only not worried about the sonar . Can I wire the two together or do I have to run a Separate wire back to the battery

I would think you could run both off that wire as long as nothing else is drawing off it. I would try it and you have a problem I would just run a new wire a size larger and tie both to it. Most important is really good connections.

Which unit are you planning on adding?

Would like the 899 but alittle out of my price range . But hate to get a598 and not be happy

I'm a believer in a fuse panel or at least a buss up front. I have a blue sea fuse panel with a ground buss up front. It's fed from the fuse panel under my console.

I would save a little longer and buy what you really want, in the long run it's usually cheaper 'cause you end up buying the other unit at a later date anyway.:biggrin

If you are looking at getting the 899 (after saving a little longer) you really need to run it on its own power cable from the battery.

CrappIemax you got a point. HumminbIrd I'm wanting to put the 570 and 398 together and get the 598 or 899 for the helm

If you knew the wire gauge size we could make a guess as to whether the wiring could carry enough power or not. Might just be easier to connect them both up and give them a try. If you end up with problems then run a separate power wire just for them.
