Wiring an aux backup light

I messed around with a simple location today using the existing bumper bolt that slides down through the hitch. It's protected fairly well by the hitch safety chain loops on departures. However, it would be game over for the pod backing up over a steep object.
The more I think about it I might just run this pod on an auxiliary switch (one that is lit, so I don't accidentally leave it on).

 

To do it "right" on an aux switch I'd need 1 of these https://caliraisedled.com/products/toyota-oem-style-reverse-lights-switch
and what else ??

 

See my post above: Wiring an aux backup light

You'd need a switch(a DPDT or SPST depending on how you want the light to act), a relay and a fuse.

 

Thinking I might just go this route;

a bit more money but easier and a nice clean set up...if this is indeed the right parts.
