Downrigger help

[dubob]

It just pulls apart. 2 pins on one side and 2 slots on the other side male/female. Might be corroded in there causing it to stick. I'd bend it back and forth both ways to see if you can free it up. Maybe put a little screwdriver blade under the rubber boot to pry it apart. Use a little dielectric grease to prevent corrosion in the future.

Grab both plugs (not cable) and flex them back and forth (think break spaghetti noodles in half) while you pull hands away from each other.
