The red & black at the control box essentially come from the battery, but via the engine. Theory being if you have a hard boat with the battery sat in a locker by the engine, you still have power to the dials etc at the wheel, potentially at the other end of the boat.
Having said that, you probably want to connect the tacho + to a Yellow. (switched +ve) so it only comes on with ignition & doesn't flatten your battery when the engine is off.
But yes, remotes loom or direct to batt are both valid, but connect via a switch & small fuse if you go straight to battery!
