Hole in console measurments are 5 3/4 in wide and 4 1/2 in tall. I'm trying to find out which graph I can buy that will fit in that hole. I've got a Hds 9 ram mounted at console also, so the unit I'm going to flush mount just needs to be a good mapping unit. Unit doesn't have to be a lowrance. I don't plan on mounting another transducer so I guess the new unit will be strictly mapping unless, I do by lowrance and it can be linked with others. My main concern if finding a good mapping graph that will fit in console hole thou.

Most 5" display models fit that cutout.
Humminbird 500, 600, and 700 series
Lowrance HDS 5 and Elite 5.

Just get one that has sonar and GPS/Mapping

If the transducer in the boat is a Lowrance with blue connector and you purchase a Humminbird sonar unit, this adaptor through Motorguide will connect that transducer to the Humminbird:

It is the one at the bottom of the page.

Will a elite 5 be decent for mapping? Or can it be networked with my Hds units?

The Elite series have slower processors than the HDS units.
You may not be pleased with the on-plane speed performance of how the maps are processed.

Does anyone know what the yellow wire is for on the power cord? It says yellow N/C

It is the "wakeup" connection for a Structure Scan box.

Here's how I did it:
