Not sure about a lift but all you need is the wiring harness and new light. The stock one on the 14's and 15's have 2 plugs the new harness takes it back to 1 plug. It's pretty easy it's all right there to see once you get the light out. Took longer to get the new harness into the little plastic holder after taking out the old one. Little plastic things that move around while your trying to slip and snap things on"LOL" After test riding my bike the other night I had to adjust it up some. Had Spazz's bike and mine side by side on a dark road to see the difference between the evolution 1 & 2and there is a little difference but not that much to go change out the daymaker right now.
This is a really easy install
