    Thanks Richard - that sounds promising. Do you by any chance know how to access the alarm control module? The main problem I have is that I haven't been able to obtain any wiring reference diagrams for the Boxster.

    Cassiebox - thanks again for the input. Good suggestions. DiscobayJoe - Actually I previously read and really enjoyed your worklog but then it seemed to stop for a while. My next step was going to be to ping some of the guys on the MP3 car forums to see how they'd done theirs. The Carnetix supply looks great. One of the reasons I got it was that I want to be able to run an extra hard drive for my entire CD collection as well as the screen, GPS etc. I guess I could take power straight off of the battery - just thought that that might look a little messy so would have preferred to tap off an existing wire somewhere. I'm not sure if I understand the concept of the switched ignition power - I'm hoping it is just a pulse (to tell the PSU to switch on)? As regards placement I also thought about putting it in the front trunk as it would be pretty neat in there. There is no Glovebox on my Boxster so that is out. My other options are a] in one of the Din slots in the console b] Under the passenger seat or c] there is a space behind the passenger seat where I believe that the CD changers go in the boxster. I'm just nervous as hell about blowing my electrics so I'd love to see how others have done their installs. If I do figure it out I am going to photo it to help others. All the other parts of the process seem to be well documented on the web.

    Nice diagram. Thanks that is a great start. So the green and black one will give me my ignition on pulse - is that correct? Its a nice idea to run straight from the battery but it might look a little messy - I'd prefer to tap off of something that is already on the cab side of the firewall. Maybe somewhere near the fuse box. There doesn't seem to be any documentation anywhere... (Actually, hold on, I've just looked again isn't that ignition switched 12V+ only for the phone and consquently only about 500mA?)

    I've bought a Carnetix P2140 power supply that provides intelligent regulated power to any in-car computer that you might have. In my case I am installing a Mac Mini in my 2001 Boxster. Basically you connect the PSU to the battery, but there are additional wires to provide a pulse start input (typically from the car alarm system allowing you to start the computer before you start the car when you open the doors with the wireless keyfob). Also there is an input labelled Ignition that I think starts the PSU based on the ignition key being turned on. I understand it conceptually but am at a loss to knowing where I can actually physically tap into these wires from in the existing car system. Can someone point me in the right direction to where I can tap into - 1. Ground 2. 12V+ (note that I need the full battery power and that e.g. the spare cellphone connector would not be powerful enough) 3. The pulse voltage signal that occurs when the keyfob is activated. 4. The ignition switch on signal. I am guessing that the PSU itself would be best mounted in the centre dash somewhere or perhaps it could go in the front trunk? I am totally unfamiliar with where the physical location of these wires are so as much help as possible would be appreciated. Here's the URL of the PSU in case anyone is interested in finding out more about this product. http://www.carnetix.com/installation/P2140...Manual_V1_2.pdf

    Thanks Ralegen - actually I hadn't seen that first thread, so I have subscribed to it. The Rainy Day site is cool but they never seem to give quite enough technical detail for me. Yeah I've never seen anything on anyone getting video out from a TomTom - part of the problem is I suppose that the screen is also an input (i.e. touchsceen) but I am sure it is technically possible. I'm sure one of these days someone is going to develop a really good in-car GPS solution based on Google Earth. That will be awesome. I've already seen the prototype that the japanese car companies have come up with. Looks good.

    Ralegen - no problem - I certainly will. I am pretty proficient in the Computer side of things but I've only just started working on the car myself. I'll try to post some photos of the install. I am doing the mac mini install because I have hundreds of CDs that I keep leaving in the car and they then get scratched! With the computer install for the price of a good audio system you get a digital jukebox with access to hundreds or even thousands of CDs, plus video thrown in for free, plus the possibility of internet access, and throw in a receiver and you get cheap GPS. All in one sleek touchscreen. The mini appeals - because it's a Mac (obviously) and the size is just perfect to fit in the dash. A drawback is that the in car software is not as developed as in the PC world and the GPS is truly awful at the moment in the Mac world. I'd love to be able to take a video out from something like the TomTom and just display it on the Mac's screen. I don't think that this is possible at the moment though. Thanks for the heads up on the MP3 forum guy. Rainy Day Garage has a few nice articles on a Mac Mini in a Boxster but they don't have any good detail on the actual installation process.

    Thanks Jon - you're right that makes sense as it's quite a large load. Two things I am really not sure about, maybe you can help. First can my connection to Ground on Carnetix side just be direct to the negative post of the battery or should it be some other ground in the car? And Second the diagram shows only one wire to the ignition switch does that make sense and if so where would the connection be?

    Folks - A little help would be appreciated - I want to install a Carnetix 1900 Power Supply to power a Mac Mini computer in my Boxster. However I've never attempted anything heavily electrical in the car before. I was hoping to be able to utilise the spare phone connector and power supply that is behind the main console (I've seen others mention it here on the Renntech forums. Attached is the suggested wiring for the install. Can I just connect the postive and negative of the Carnetix to the positive and ground of the phone connector? Or is it more complicated than that? And if I want to add the ignition switching what do I need to do? Any advice or better still photos highly welcome.

    I have a re-occurring problem with my window washer tank - the hose somehow keeps working loose. When I refill the washer tank on my 2001 Boxster the water runs straight out again. Does anyone have any pictures or description of how to access the washer tank and rectify a loose window washer hose to the window washer tank? Thanks!

    Thanks Perry, that helps a lot. Off to do a bit of Google research on removing the console, AC and HU. Happy motoring... :thumbup:
  11. joesan
    perry190 - thanks for the quick reply. Your setup looks sweet! You seem to have done exactly what I want to do. Is it a pain to move the aircon controls to the position where you have moved them to? I want to move my Headunit and the AC controls to the lower portion of the console. PS I am in London so pricing in £'s is cool. Did you get the replacement trim piece from Porsche?
  12. joesan
    Hi Perry190, I am looking to install a touchscreen unit in the slot where the A/C controls currently are so I am interested in your question. Did you get anywhere on this? If so can you post some pictures? I am installing a Mac mini into the car - I am good with Computers but have very little experience modding cars! Joe
