I did this mod to my 2003 Tundra and a coworkers 2003 Tundra(for lunch

)
the lunch almost took care of my club membership for a year.
mine has been done for approx 6 months and his for approx 3/neither of us has experienced any problems whatsoever
The relay isnt exactly the same as pictured in the Mod forum
