    Rewiring a Series 3 - advice required

    Hi all,

    the so called "wiring" in my series 3 is a combination of old gunky electrical tape, screw connectors, burnt fuses and twist-together bodge jobs held together by a few yards of scrappy copper wire.
    There are probably left overs from two or three sets of driving lights - not to mention all the hacked-out army black out light connections etc - floating around in the engine bay. The fuel guage has never worked, I've just lost headlights altogether, and my spark gets weaker daily.
    I'm at my wits end!

    I'm looking at something like this generic wiring loom as an alternative.
    i've never delved this far into a car's wiring before, let alone the hell of Mr Lucas.
    Can anyone tell me if the above would be suitable and within the skills of a moderately capable young man who can read instructions?

    If you are thinking that sort of money, have a look at AUTO SPARKS
    you can get exactly what you want and just plug it in.

    For the sort of money listed in the "buy now", I would be looking at contacting a specialist such as Vinwire ( Vintage Wiring Harness - High Quality Replacement Automotive Wiring Harnesses), but alternative approaches would be to do it yourself, working from the wiring diagram, get a second hand loom from a wrecker (you might find one better than yours), or just ask a local autoelectrician to quote on it.

    Vinwire don't do series 3. I spoke to them at the Toowoomba swap meet.

    Thanks Guys,
    I'm a little way off from this job in my S2 but it's nice to have a head start.
    Good luck with yours 45tr0.

    Have to agree with John here, nothing beats one specifically made for the model.

    Series 3 individual harnesses are still available OEM from many of the UK LR specialists. You may get away with working out which of yours need replacement and start there. The fuel guage may just be as simple as the wire to the sender has disconnected, broken or burnt, although the guage or sender itself may have failed.

    Vintage Wiring can be expensive, expect over $500.00 but they do an excellent job. However you will find the pricelist doesn't currently list the S3http://www.vinwire.com.au/pdfs/JKL-pricelist.pdf. Although when I spoke to them at the Eastern Creek Classic last year they suggested they will replicate a harnesses from an original and the wiring diagramme. They even make them from very damaged harnesses with missing bits or even just the measurements and the diagramme. After this process, they then add them to their catalogue. Maybe one of our Melbourne members may supply a harness from a wrecked S3 for them to copy.

    $1500 - $2000, and that was the one out of three in town who would even consider the job!
    the others said that private work isn't worth their while anymore because of the resources boom... (ah the joys of the northwest!)

    Looked into the Vinwire option, but this situation requires a more urgent response than the lead-in of them borrowing and replicating an original loom.

    The autospark option looks reasonable (more expensive but vehicle specific).

    Thanks for the advice guys, will mull my options.

    Yes, I see the problem with your location! Depending on your expertise, doing as Diana suggests and repairing your existing harness may be your best option. Another possibility, again depending on your expertise, would be to remove the harness and duplicate it yourself - a fair bit of work, but not all that difficult and not very expensive, particularly if you do not attempt to duplicate original colour codes and make use of off the shelf items such as multicore trailer wiring.

    Tell us what vehicle your vehicle was originally 88" or 109" and/or Station Wagon, 4 or 6 cyl engine, vehicle suffix number, engine suffix number and did you have a choke warning light?

    For example, the OEM main harness for a 4 cyl with choke warning switch (part number 575373) is available from John Craddock for GB£135.00 plus shipping via an internet order system.

    This would be a good one to start with as it has the all the wiring inside the dash panel and up to the headlights. But not the engine harness or the rear tail lights etc.

    its a 1980 109" Series III GS (ex military) with the 6 cylinder. Engine # 94130728C.
    No idea about a choke warning light - if there was one there certainly isnt now!
