umm yea there's splicing. that's why it's called a retro-fit. there's also molding and drilling and other fun stuff. you have a mitusbishi wiring harness connecting your headlight housing to the car. inside the housings are 9005/9006 plugs for 9005/9006 bubls. i seriously doubt any retro-fit off of ANY car would ever be plug and play. HID kits are only plug and play because they plug in to the bulb socket (9005/9006 in our case). the HID off some other car would have whatever custom connectors that particular car/model uses in their wiring harnesses.

btw you realize HID kits are just bulbs and ballasts, right? as in no projector lense. i sported one for a while and it looks neat but obviously our reflector housings were never made to hold HID's. if you're gonna buy a kit you should probably AT LEAST buy a cheap projector headlight off ebay or somethin too.
