well i did it on my kawi and it was simple, a lot of them say plug and play but i ended up with the wrong connectors but i didnt have time to wait so i just spliced them into my stock harness and then soldered them and then heat shrunk, they worked fine for about a year or so, then they started blinking and one would go out! so i got to talking with ononewheel and he installed the same type of kit with a set of relays for the hids and hasnt had a problem, its a very cheap and simple upgrade and well worth the extra light, i think my kit was 55$ ship for the HID's and then the relays were like 11 or 13$ shipped, i will be hooking them up as soon as they come in, they come with a male and female to connect inline with the ballast and than u get power direct from battery .
