anyone can help me with the wiring? where should i put the on and off switch for it?

 

I would say dont do it !! but from the sound of it you already purchased them .. depending on what you want them for will be the deciding factor on wiring . Do you want to run them with your headlights on off or both ?

 

i want to run them when head lights are on and off. and maybe singles. why do you say not to buy them? but yea i already did.
