  • sending 12v signal to relays

    Hey guys

    i have no idea about running a computer in a car but i think i like the idea

    i have a 4x4 and am wanting to make a few electrical mods.
    for a simple example i would like to have a light in the back, i would normally just wire the relay to a switch.

    if i had a computer could i have a "rear light" button on a touch screen that controls the relay turning the light on and off?

    cheers

    Have you looked in the FAQ yet?
    How about the Wiki?
