This was the most helpful post when installing HIDs in my 2014 gmc sierra 1500 SLT. I have never had to install and additional relay harness for HIDs they have just always worked until now....For my headlights I used a 9006 Genssi 5000k kit (the 4500k kit will probably match the existing LEDs a little better) off of Amazon for about 40 bucks I have always used DDM tuning but I was tired of waiting a month for my lights. Mine wired a little different than described in the post. I was using a double relay harness and still had to reverse the wires coming from the stock plug. (Not a big deal) I also did not use a code eliminator, I bought one and they do not work when I install it. They do not buzz or flicker without them For my foglights I ordered GP Thunder 5202 cree LEDs because I didnt want to melt the fogs. They cost about 40 bucks and were plug and play and are 5k white. I first recieved some phony brand and they were between a 6k or 8k and those were returned. Both took no longer than 5min to install Some other problems I ran into was getting the airbox out. Make sure you unplug the MAF and ALSO unclip it from the box (Makes it 100x easier to get in there) Then to take the airbox out after you unhook everything and take the filter out. Just pull up on the lower part of the airbox and it will pop right out. There are two rubber plugs holding it in place. I have light abover the cutoff so I just need to reach in and adjust those as described earlier in the post. Ill try to get some pictures up soon and an exact diagram of how it worked in my truck. But seriously great write up, thank you.
