I used the painless and was very happy with it, everything is clearly marked. The only thing about the painless harness was that I had to pull the wire loom off the to sort out 2 pink wires in the engine compartment. So while I had it apart I replaced one of the pink wires with a different color.
Also the ground wires for the tail lights need to be grounded to the lights not the frame.
