I just finished the same thing , Looks great .
1) 10mm socket wrench
there are 6 nuts, take them out push up on the studs (they should come up fairly easy) undo rev. light wire connectors and connector for plate lights (on left side) . take off clean with rubbing alcohol , mask off area and clean with alcohol again .
What kind of paint are you using ?
I recomend VHT night shades spray tail light tint .
