So I got that ^ wiring harness for my H4's and didnt listen to the top negative review and my fuses blew. Well not so much as they blew as water got on them and ruined them. So I was just wondering what everyone was using for there fuses since a replacement fuse is about 12 bucks for one of those. And that half of what I paid for harness!

Any help would be great appreciated,
Thanks,
-Zack

I wounted them behind the stock headlights, Wires up. Like the circle whole was up towards the top of the engine bay.. Ive had it on since april and it was fine until the other night when I tried turning them on and it didnt turn on. So I just plugged my autopals into the stock harness, which I dont want to do. And the grounds and positive wires are good. I checked them both yesterday.

Yeah It looks like there mud on them and there corroded and stuff. I dont know if you can see it in the pictures or not..Do you think I could just wire up a new 30A relay in their place?

Did you put any di-electric grease on them? That will keep water out...
You should put the grease on any connection outside of the vehicle, including the engine bay.
