    Please go to auto store, purchasing a add a circuit with fuse holder. than you will be able to turn on the light when your truck start. It is easy to do it.

    Dont forget to check out http://www.tacomaworld.com/forum/technical-chat/6525-diy-wiring-after-market-lights.html

    The basics, since it sounds like you're connecting the lights directly to the battery when you want them on, is to get a relay. A standard Bosch/Tyco relay is going to be the most common.

    Hook up 30 to the battery. 87 to the lights. Leave 87a alone, unless you want something to have power when the lights are off. Hook 85 to the ground, and 86 to whatever you want to activate the lights.

    Some common options for what to hook to 86 would be:
    * the headlight fuse (using a fuse tap in the engine compartment), so the lights are only on when the headlights are
    * a switch run to the cab. The switch can be hooked to anything with power, be it directly back to the battery (so you can activate the lights at any time), the acc fuse in the cab (so the lights can only be turned on with the key in), or even to the high beams (so the lights are only on when the switch is on and the highbeams are on)

    Note, 85 and 86 can be swapped, as it just requires a positive and negative to activate the relay.

    Dont forget to fuse everything. You'll need two fuses. One going between the battery to the relay, and one between whatever you're using to activate the lights to the relay.
