How to connect a rear fog light

[cashville]

I want to place a rear fog light on my h2, like this one:



I already have the fog light, and the switch to turn it off and on, to place near the lights switch.

I was going to go to a shop to have them place it for me, but if it's something simple, maybe I could do this work myself.
Anyone can tell me how I would go about doing that, so I can see if I can do it myself?

Hi you want it to be turned on and off with a switch or with the truck lights?

Hi do you have a relay to? pm sent to you.

I just replied to your pm.

I don't have a relay. The h2 from the photo is also mine, and I want to put my fog lamp like in that one, because by law I need to have a rear fog lamp.
