You can get the connector for a lot less on Ebay. I just bought 50 of them for my M12 adapter board (which would work with the Furuno). Unless you do a PCB, wiring to the connector will be a rather painful, unreliable experience. https://www.ebay.com/itm/10pcs-Pitch-1-27mm-2x5-Pin-10-Pin-Female-Double-Row-Straight-Pin-Header-Strip/173004816072?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649 There are other sellers... Also, Adafuit sells a pre-made ribbon cable with the connector on each end for $3. You can cut the cable in half and separate/strip the conductors. I was planning on shipping my M12 breakout board with male and female connectors (unmounted) so you can chose a rigid (female) or flexible cable (male) connection to the board. https://www.adafruit.com/product/1675
