I think I added this to another thread somewhere that has the parts I used but I purchased an extra extension cord for mine and drilled a hole behind the porch light. Then I heat sealed around the connector and mounted my lights to the bottom of the gutter and behind the awning. I used a thin coat of silicone over the top for good measure and a blob on each end to hold it still.
On the inside I used a low voltage face plate with a filler plug. I drilled a small hole in the plug and snapped it into place after bringing the plug through. It's all tucked behind the TV when it is in the camper.
I replaced my porch light bulb with a LED and put the remote sensor to the light strip inside light dome. Here
is a video of it in action.
I'll try and attach a few photos.
