No lighting coil since it pulls off the battery. The SEM stators had pretty good output as I recall. Baja Designs never had a problem with them. If I had an 04-08 I would consider a stator upgrade.
If your buying the xenon, yes its pretty much plug and play. Make sure you get the trailtech headlamp switch, it should make it easy. Plug in the switch and run 2 wires to the battery.
