Thanks for the tip. I didn’t even think about opening the holes. And as you can see in my previous picture, I’m running all the wires from the remote switches to the terminal blocks. Just behind the control panel. I will then run 18-5 thermostat wire from the block to each switch. 3 of the wires are for the switch operation and 2 are for running to my 14v auxiliary power.
I had not thought of doing that! Good on you. And the thermostat wire is a good choice. I used CAT-5 Ethernet cable to keep the colors straight.
