I got aftermarker led sidemarkers and I have no Idea how to wire them. This is a ground, 12v, and turn signal wire. Any ideas?

 

If you have the 3 wire version then it's ground, bright , and brighter but you can only decided with bright or brighter. Test it out by directly hooking it up to the battery and decided which one is best for you. I forgot what color represent what.... I tapped mine into the signal wire from the bumper lights
