Switching out 01+ tails is straight plug and play. If you go with LED, they come with Resistors. Beware if you get a brand like Depo, The resistors are bad and will heat up and cause a burning smell from the trunk. Just throw them away. Most people just remove them and live with the busted taillight alert on their dash.
