Hey guys, I've landed a good deal on oem 06 headlamps in good condition so I'm going to do the swap into my 04. From the 2 different write ups I've went over it seems fairly easy & worth it. My only question is, I actually plan on doing an HID upgrade to them with TRS, so with that will I still need to get all the wiring harnesses from amazon that is required if you're just doing a straight swap? My apologies for what is probably an easy to figure out question. anyways, thanks in advance!
