I have purchased a 1987 rinker v190, it came with a Uniden ff3300 fishfinder/GPS, on the back of the FF, there is a place for 4 cables, there are only 2 in the boat, (2 pin, 3 pin, 4 pin, 5 pin) 2 pin and 5 pin are missing. can i get these anywhere? i have contacted Uniden, they no longer make FF's.
