Just installed the ddm kit on my nytro.
Couple of things, I used the supplied harness from ddm, wasn't willing to pay $40 for patch cables just to eliminate a couple wires! If using this harness and you ground the 2 wires to the lower steering loop like grizz suggested you'll need to take a drill bit and make the ends of the ground terminals larger in diameter. No big deal just a heads up. Everything just plugs into place and they are waaaaaay brighter than stock. The $2.99 mounting brackets for the ballasts work great, 3 little bolts/nuts (supplied) to secure the ballast to the supplied bracket and then mount to lower air box bolts.
35 watt, 4300k and not even a hint of blue! Just how I wanted it!
