I am trying to install HIDs in my fog lamps on my 05. However after hooking everything up, they won't turn on... No Suprise to me cuz I left the fog lamps unplugged with no bulbs at all for about 6 months and I'm guessing water got up into that fog light wiring harness? Idk but how do I fix this?

Do you have a volt meter? Test the connection to see if its showing anything. Not sure but maybe check fuses for the fogs. Those would be thee first 2 things I'd check.

1. Go back and hook up regular fog lights (make sure the regular lights are in working order) and see if they work
2. If you know the lights work, but they dont light up, you gotta check the harness with a multimeter; see if your getting power through it...Ive got the Exterior Lighting Fog light Diagnosis and Testing if you need it. If you want it, PM me with an email address and ill give it to you. Its 160KB

I just now stuck a test light in the two holes in the harness. It didn't light up at all. Or do I need a multimeter only?

I can give you all I have on the topic if you want. Ive got the Exterior Lighting Fog light Diagnosis and Testing if you need it. If you want it, PM me with an email address and ill give it to you. Its 160KBYa, now you want to pull out your multimeter and check. Also like the previous poster said, check the fuse as well

Will do. And what could running the harness unplugged do? Like how could that make my entire fog light system not work?
