hey dude i don't know if this helps but i added stock 04 hid to my silverado since i did a front end. I don't know how mechanically inclided you are but im not that much and i got mine to work. I bought the harness complete harness for the 04 escalade at the dealership and then ran it connected it to the lights and the ballast and then took apart the fuse box that is inside the engine compartment and unscred the bolt that holds in a green connector and plug in the one from the dealership that i ran and put it all back together ziptied everything and turn on lights and they worked. hope this helps.
