I suggest NOT going to the molex plugs. They are a failure point. Pinning a molex plug is tedious. You need proper pin and crimp tools. You can't wing it. I haven't done it in this century.
If you want to be able to disconnect the panel , use individual disconnect terminals. They are easier, they give you ability to swap to test when troubleshooting

I had to bypass a molex for the cabin lights and now the livewell is also giving a problem. Voltage gets thru one plug but doesn't reach the pump.
You might find as I did that they are green. Maybe yours are better without the constant salt air.. Many wires go thru multiple plugs to get where they are going. I had there different plugs with wires that went to the switch panel. I rearranged them so that I can easily lift up an turn over the panel with wires attached.
I am going to bypass the molex for the main 12V feed. Go straight short pieces of 10awg from the terminal blocks under the dash.
There are two unused light blue wires to the aft bilge. I think they were for OMC motor oil tanks? Might be able to use for livewell. Otherwise I have to fish a new cable.
