That's the problem with buying them on Ebay. The people that put those kits together really don't know what they're doing.
It's either a problem with having no brackets/incorrectly cut ones, or the wiring is too short or something else is missing.
You're gonna have to probably make your own if you're going to stick with what they gave you.
You MIGHT be able to go by a dealership and see what they'd charge, but I highly doubt they wouldn't try to sell everything together to you, like the entire fog light kit and rip you off.
