    Picked up a TRD Pro grille, Cali Raised LED light bar mounting brackets, and 42 inch light bar. I don't have any blanks for any switches, so I went with controlling the light bar with my fog light switch.

    First step: https://www.tundras.com/threads/diy-fog-light-mod.371/#post-5947

    Gotta do the mod so that your fog lights are on with headlights, but can still be switched off. So, you couldn't attempt this with the bent and grounded pin on the fog light relay.

    Second step: Install a couple of relays as per the picture below

    Last step: Hook it all up

    This leaves you with the following lighting options.
    All lights off
    Lows on, fogs off
    Lows on, fogs on
    Highs on, fogs off, light bar off
    Highs on, fogs on, light bar on

    You CAN"T do Highs on, lights bar on, fogs off or Highs on, fogs on, light bar off

    I don't remember the wire color for the +12v on the fog light, but its the one without the stripe.
    I think that the +12v on the high beam was light green.

    That's not a bad idea. I did mine with just the highs. I don't have fogs on with the bar and ditch lights, but who needs em with all that light? I do like the fog light switch to turn them off though.
