hey everyone. new to the site. a friend of mine told me about it.

my girlfriend has a 2003 audi a4 sedan and i wanna hook the fog lights up to the parking lights. currently you can only turn the fogs on when the headlights are on. theres a lot of sites that show diagrams and ways to do it but all of them are from canada and i guess the fuse layouts are different then u.s. cars. if anyone has any ideas, diagrams, anything that can help me out lemme know. thanks!

On the back of the light switch meter the wire that turns on the fog lights. Cut this wire and tape off the switch side and wire a relay that is triggered from the parking light switch. The parking light wire is GRAY OR (BROWN / WHITE).
