I am new to TOH and look forward to using it as a resource more in the future.

My current question is this.

I received a Exterior Lamp Post for Christmas and now my wife wants to install it. I read the article previously posted for installation. I understand the electrical for some of the installation but not all.

Can someone give me instructions / options. What is the best way to tie the lamp post electrical into an existing interior light switch located at my backdoor?

Can I drill a hole through the foundation wall then through floor into the base plate of the exterior wall where the light switch is located and then connect it to the switch?

PLease help.
