Do you have a drawing that shows where access is required and exact locations of motor and supplies?
There is one connection point for electrical and this connection point is on the long side, under the topside keypad. If you are going 220 volt, you hard wire to this point. You can also hard wire a 110 line, or have us put a 110 volt GFCI cord on the spa.
All spa panels can come, as there is a structural frame underneath. This means you can bring your electrical cord into the spa from any desired position. If it is not near the connection point, just fish the wire around the spa until you reach that connection point.
