    None known. This is a turbo diesel automatic.
    I have a lot of intermitant problems with lights, both interior, and most importantly, exterior. At the moment I'm trying to replace rear bumper lights with after market direct connect. This removes the plug and socket, the most likely problems.
    Panama is wet and very humid, so...
    I need color codes for the lights first, or a full wiring diagram, I don't think that lights will be different from the USA gasoline models.

    Not sure about 4runners, but i bought a laminated set of Foxbody Mustang wiring diagrams off Ebay that are 11x17" and laminated. Maybe search Ebay for "2003 4runner wiring diagrams" and see if anything comes up.
