Question 1 switch operating 2 outside lights both operated with 1 photoelectric switch

I am wondering how to wire one photoelectric switch in my new outside lamp post and one outside porch light so that both will work off the same switch and the photo cell on the lamp post.

The photoelectric switch in the lamp post has black, white and red wires. Both lights are for 100w incandesent lights the photo switch indicates 300w. On the photo switch it indicates that the red wire goes from the photo switch to the black lead on the post lamp. Then the 2 blacks together and the 3 whites together.

I have new 12gage wires running from each object to a box in the basement. The objects are the lamp post(with photoelectric switch), inside switch, and outside porch wall lamp.

Any ideas would be welcomed. Do I need to change the lamp post wire to a 3 way-wire?

You will need to run 12/2wGrnd normal Romex cable from a power source to your light switch box and a 12/2wGrnd UF cable from that light switch to the post light. In the light switch wire nut the whites together and the bares together and connect the two blacks to the single pole switch. Then you will need to run a second 12/2wGrnd UF cable from that post back to the second light fixture. Wire nut all the whites together including the white photo cell white wire and the white light fixture wire and the two white wires of each 12/2wGrnd UF cables entering the post all together under one wire nut. Connect the black wire of the 12/2wGrnd UF cable coming from the light switch to the black of the photo cell. Connect the red of the photo cell to the black wire of the light fixture and to the black wire of the UF cable going to the second light fixture.

IN the second light fixture connect black to black white to white green to bare.

You will not be able to make the sytem work as you have them all going to that junction box.

Replacing the cable from that junction box with at 12/3wGrnd would work if all the cables are coming to that junction box from each light fixture, power source, and switch, but that is another story.

The above is the least confusing and easiest to wire normally.

Hope this helps
