  • +12 ACC power?

    hi all, I'm thinking of hooking up an Audiovox FMM100A FM modulator to an '07 Honda Odyssey. The modulator's wiring instruction is as follows:

    I'm not sure how to connect the "+12 ACC power" (I think it means accessory power?). Any ideas?

    Also, is the "line level" input going to be a problem if my source is the headphone jack of an mp3 player? (Would an attenuator be recommended?)

    FYI pictures of the car's dashboard can be found in the following web pages:

    +12ACC is switched power. ie when you have the ignition key in the ACC position, you should have +12V on that wire and should be 0V when the ignition key is switched off

    btw, the modulator pic is broken.
    Never let the truth get in the way of a good story

      Thanks. I've fixed the modulator's pic.

      Would this switched power be a standarized plug for all vehicles, ie. the same as, I'm guessing, the green plug in the following pic (2nd from the left)? It's the rear of my stereo and I'm guessing that's the power plug.

      If so, I assume a simple Y-splitter can be used to power both the modulator and the stereo?
