Is there a step by step on how to do this?1. Dont get HIDs unless you're going to retrofit. If you do, 4300k has the most usable light(as far as the percentage of the light that is output in relation to the color spectrum the human eye can see).
2. You can wire the fog light switch to the defroster wire or just wire it to a switchable 12v source. The extra connectors of the under dash fuse box work well.
