    Where is everyone taping into to get your 12volt power from? Is there a certain fuse that is better then another one to use. Want it to power off when key is off.
    And how are you taping into it? Using a fuse tap? Or do I need to run a fused wire right from the battery?

    I don't have a light bar yet but the proper way would be to use a relay. The main power source comes direct from the battery the secondary source that goes through the switch to the other connection on the relay would be accessory power. This power can be pulled from the fuse box under the dash. For my amp accessory power i pulled from an open slot that happened to be accessory power.
    Used one of these

    We advise against using an Add-A-Fuse or similar as the main power for Aux. Lights. A wiring harness w/ relay and fuse directly to the vehicles battery is the best way to go. This keeps extra strain off of the OEM electrical system. Many of the circuits were only designed for 7.5-20Amps.. Adding a light bar on top of that could overload the circuit.

    An option for you is to find a keyed 12V source and use it as the trigger for the relay. It will turn on/off when the key is on/off and will only use the OEM circuit as a trigger. Not a main power source for the light.
    Good Luck with the project!

    Thank You,
    Bailey, Baja Designs

    There is a killeeeeeeer right up on a Tacoma forum. It's saved to a computer I don't have so sorry it isn't a lot of help. If you google "how to wire LED" or something and one comes from a Tacoma forum it's probably it... You'll know bc it gives every detail possible and pictures. It's what I used to do my bars.
