RL80-to ARAMAR B744VL

[snfriends]

Moved a lightly used RL-80 to BluewaterSportfishing boat. It has installed a large Aramar B744vl.

What cable converter do I need to go from the Aramar to the RL-80? I also have a DSM300... What cable do I need for the DSM-to-Aramar, then fromthe DSM to the RL80? or to I punch out the finder and use one that can connect directly with the RL-80?

(I think that I need two (2) spearate cable connector conversion to make the DSM work in this system...)

Thanks
