I connected the black/white wire to the brown wire on my headlight switch. Now when my switch is on parking lights (parking lights never worked) it makes a buzzing sound somewhere near the passenger airbag. What did I do wrong?

 

And the headlights seem to half light up

 

Your back feeding the headlight relay.

 

how do I fix it?

 

Undo the headlight mod and fix the parking lights.

 

There's power going to parking lights they just are not coming on???!

 

Replace the bulbs, if the bulbs are ok, the sockets are bad.

 

And when my head lights were on 4 white LEDs that are in the parking light/turn signal piece (from my after market headlights) turned on with my headlights???i want that to still happen but without the bussing? Any ideas?

 

and I have led turnsignals it didn't work when I had regular bulbs either

 

Post a picture of your front end please.
