    Unhappy Installing On/Off Switch with Opus 90W

    I have my carputer up and running with the OPUS 90W Power supply. I want to install a toggle switch to turn it off and on as needed. I have a toggle switch from Radio Shack, but I don't know how to install it. Do I need the 2 prong switch or the 3 prong one? I have a 2 prong switch now. I think one prong is for positive and the other is for ground. If I already have the ground wire from the Opus hooked up to the battery, do I need to splice it hook it up to the switch? My idea was to cut the red wire from the Opus that links to the positive baterry cable and put it on one side on one of the prongs and the other side of the wire on the other prong (Don't Laugh). I am not sure if this would work. Any help will be greatly appreciated. People at radio shack managed to confuse me even further. I am sure that it is very easy to do, but I want to make sure I do it right.

    You do not need all that, looky here, what I did. If you can get 2 prong, that is even better.
    NO PRONG SET UP(I might be wrong here)
    --- run the turn on blue wire from the car receiver (aftermarket) and connect opus' blue wire(ignition wire) to it. So if you are making short trips, do not turn your radio on and the computer will not turn on. however, you can not have your computer on when the key is out of ignition, which makes sense to me ebcsue I dont need the caputer on if the reciever is off and no sound is coming out.(One thing I am not sure is if the receiver lets out 5v or 12v, I think 5v, it could work...I am doing/testing that next week)

    2PRONG SETUP:
    ---version1: thin wire from battery(+) into FIRST prong, and the blue wire from the opus into second prong. the computer turns on at a flip of a switch whenever, whereever, no key needed. (I dont like this set up, because if you have an after market radio that the computer sound is connected to, then you will here no music)
    ---version2: The blue (external turn-on)wire from the battery to one prong in the switch, and the blue wire from opus into another. Makes more sence, works only when the radio and the key is in, alogn wiht a flip of a switch. This also allows you to listen to the radio on the receiver, with your carputer on. I like this even MORE!...

    Hope this works and makes sense...I will be testing this when I get my car from shop good luck buddy

    Also, 3 prong, all you need is 2 prongs, so use the two prongs out of three.
    The third one is for the light to go on when you switch on. Anyone care to explain how to make the light work?

    Hope non of my information is misleading, tryign my best, waiting for confirmations from other members

    Third prong connects to earth to turn the light on if the switch is in the 'on' position.
    It's a good idea to connect this switch between the remote output on the head unit and the acc. input on the Opus.

    do you mean 'to ground'? What do you mean by earth?
