yeah, i've done halos on3 or 4 or my trucks now, lol. some are definately easier to get at, and the dodge was probably the hardest because of the confined space they give you to work with when splicing it in there. As for the rewire, you switch around a couple of the wires for the headlights to get them to work better. if you switched over to HIDs right away, you might not of noticed. is your hi beam indicator light on while your low beams are on? If no, its wired right, if yes, its wired wrong. The factory wires these lights how dodge wired the sport models, which came with 4 lights to begin with. since ours came with 1 to begin with, they don't work right. They look like they do, and they switch from high to low, but they don't reach their full potential. Either way it doesn't matter to me, i can rewire them if they need it. what are you looking to get out of them?
