    Hello Peter...

    From one 1982 QPIII owner to another - Very Nice Work!!!!

    I always thought that there was NOTHING magical about those black boxes.
    In fact, some of them are down right simple inside..

    Please continue to keep us informed on what you find and solutions!

    Did you ever post pics of your car? I can't remember (first its the black boxes that go, then its the mind! :) )

    I didn't yet start posting photos of my car but I probably should!

    I'm attaching below a picture of the electric mod I described in my previous post.

    I've also posted two pictures of what's inside that Tedel 103 black box on the dedicated thread, for those who would be interested :

    Other works I've done on it so far:
    - bare metal repaint in original Blu Sera Metallizzato (many thanks to those who posted the paint color codes)
    - new tires: Michelin XWX 225/70 R15
    - new automatic antenna with FM/DAB splitter (to avoid sticking those horrendous glass DAB antennas on my windscreen)
    - new autoradio: Blaupunkt Bremen SQR 46 DAB (period-correct look with Bluetooth, USB, AUX in and DAB radio)
    - new battery: Odyssey PC 1500-34R - great improvement which I highly recommend, I confirm that this model fits in the battery compartment of a QP III, and that's the highest/best specs I could find within the correct dimensions for this car
    - A/C conversion to R134a - fortunately, my compressor was still functional so A/C now works very well
    - new ignition leads (cavis) and new spark plugs
    - carbs cleaning, rebuild and syncing by a professional carburettor specialist (see pictures below)
    - grease the electric windows motors & mechanism to avoid premature failure
    - realign two sagging doors which caused a lot of air noise when driving above 100 km/h

    Pending works scheduled for the coming weeks/months:
    - replace the starter motor with the RobbMC mini-starter - my original starter is still working so I'll save it as spare but I know that's a common failure point so would rather anticipate (I've already received the new starter but both my mechanic and myself are quite busy these days so will do that when we have a moment)
    - reconnect the vacuometer gauge - any advice on that would be highly appreciated, I'm still trying to track down the vacuum hose and find where to reconnect it
    - reconnect or repair the centralized locking switch in the driver's door - interestingly, turning the key in the passenger side door lock (or pushing the button next to the steering wheel) will activate the centralized locking system and open/close all 4 doors, but the driver side lock seems somehow disconnected or dysfunctional and therefore I can only open/close that door when using the key
    - I'm certainly forgetting a few other things
