I cut off the end of the terminal end of the original cable and put one male and one female bullet connector on the two appropriate wires. You can figure out which connectors go where by checking the continuity from the old connector that you removed to the wire ends where you cut the cable. I also marked the boat side terminal with a pocket knife so that I would know which of the four pins and sockets to use on that terminal. Both of my penns have been wired like that for about ten years now.
