Just received my Xenon fog kit ( xtec ) all seems well made, but not sure of how to install yet. I guess the plugs will be self explanatory once I get my old fogs out and look at them (2000 323ci, 9006/HB4 bulbs). My only concern is where to mount the ballasts. They seem a little large to "tuck" in somewhere dry and out of the way. Already seached but could not find any info. Any recs. from some one with same/similar mod?
