I have mine inside the leg at the front. I did extend the E stop to the machine front along with making power switch for both the control box and spindle. I did an above drag chain and the wiring was just long enough.
Others I have seen extend the cabling would just caution to make sure to extend shielding if it has it. Other option is to source the matching bales and make extension. For the steeper, limits and touch sensor those cables can be sourced has extension on Amazon. Search for gx12 connectors than just match the PIN numbers.
