Bro, mashAllah, apki city boht pyari hai... Allah nazar e bad semehfooz rakhe...!
bro, ab ye switch wala waqai masla hai. U have to find a place for the CNG switch... other wise, there are three options for You:
1- Simply install the fog lamps in your bumper. Donot make any wiring connection. Because fog lights main se koi itni khaas light to aati nahi k driving improve hojaye etc etc... Just use them for "LOOKS" 
.
2- If you really want them to light up, then u can directly connect them to ur parking lights. Is case main aap inko parking lights k saath off nahi ker saken gey.
3- Use some other after market On/off switch and hide it somewhere in the dashboard where its easily accessible.
Also bro, in lights ko install karney se pehle ek silicon glue ki tube ley kr inki sides par laga den. Kyun ke in ligts ki pacing quality is not that good and water enters them. they get dirty very easily...
i have put silicon on many of my cars' fogs and they were never dirty... even I used the cheapest ones in the market. :)
