    What do I have to 'break'?

    Dear all, yes another newbie....

    I've got quite a lot of electrical / computing knowledge, however, my knowledge of car electronics is limited, so watch me make a complete fool of myself.

    Ok, so I'm planning on putting a carputer in my girlfiends brand new Jeep Liberty.

    If I put in a system that is neat and tidy, and gives her a vast number of MP3s and GPS navigation to stop her from getting lost, then all would be well. However, if in the process I trash her car, including screwing up electronics and stuff then I'm going to be ... well, in trouble.

    So, it would appear that the OPUS power suply is the way to go with automatic power on and automatic standby. I'm planning on putting the comp. in the rear (trunk / boot). So, the questions are:

    - what wires do I have to cut / splice to get this to work?
    - what is the recommended way of joining these wires?
    - what grade wire do I need (presuming 50 Amp wire)?
    - how about fuses?
    - Anyone with specific knowledge of the Jeep Liberty?

    Thanks

    Andrew

    I'd say don't do it.
    If you're gonna do it, trash your own car first and make it work with your car, then once you've gained that knowledge and experience, you may or may not want to add a carputer to your girlfriends new car.

    First of all like they said don't cut wires. Ive nearly completed my setup without having to cut my cars factory harnesses at all. Secondly... Don't do it. We love our car computers, because we know how they work. We know all the little ins and outs of them. When they break or don't function as expected we know why. Or atleast can figure it out with a little help.

    What your girlfriend needs is an end user package. She will pay alot of money for it but that money is for R&D, reliability and support. Take it from someone that works in Support it will be nothing but headachs to put one of these systems in someones car that has limited computer knowledge.

    Ok, thanks guys for the advice. I should have made it a bit clearer that I also driver the car, even though it is hers.

    Athough I am some what happier that I don't have to cut into any wires!

    Can anyone direct me towards a website that may have wiring diagrams for cars / jeep liberty?

    Also, you talk about the accessory power line? Would this be the one that would normally connect to a CD Changer etc?

    Thanks

    Accessory power line is a 12V line that is live when ignition is on.

    Ok, so the accessory line is hot when the iginition is on. For the OPUS supply I would also need a continiously live line as well...??? Would this also be available in the same place as the accessory supply? (Again, so that I don't have to cut any cables.).

    you can use radioshack wire-taps to get any signal you need without cutting wires. Not the best method in the world, but does the least damage IMHO.

    If you want to keep the factory head unit, then get a male and female factory adaptor, then you could tap all the wires without splicing/cutting into anything. In an automobile, you should always sodder your connections. Here's the wires you may need.

    12volts red & pink/black + ignition harness
    Starter yellow + ignition harness
    Ignition red/blue + ignition harness
    Accessory black/orange + ignition harness
    Second Accessory black/white + ignition harness
    Keysense lt. blue - ignition harness
    Power Lock pink/purple - back of fusebox
    Power Unlock same wire as power lock
    Lock Motor orange/black 5wi back of fusebox
    Unlock Motor pink/black 5wi back of fusebox
    Door Trigger - right of st column, blue plug
    Dome Supervision use door trigger

    Hood Pin brown/tan - conn. 1, pin 6 @ BCM
    Trunk/Hatch Release orange/pink - conn. 1, pin 17 @ BCM
    Factory Alarm Disarm lt. green/orange - conn. 2, pin 9 @ BCM

    I wouldn't do it unless you guys are really steady and have some good history. Who keeps the carputer if you guys breakup. I have had to do a lot of work on mine including a custom dash so now a headunit wont fit. Only a 7" LCD. I know it sucks to think about but you have to plan for the worst and hope for the best. Now that i have mine installed in my car my GF wants one in hers becasue she thinks it is so cool, however i wont put one in hers becasue of the risk of screwing it up

    My 2 cents
