Hi everyone,

Last year I became an owner of an Alfa Romeo Giulietta. She’s a beauty and haven’t had a single issue until recently.

Long story short, went for a service/MOT. Failed the MOT on rear lighting issues that have been diagnosed as Tailgate wiring loom issues (broken wires). I have been quoted £705 by this garage to fix the issue...:oops:.

I have read past discussions, and wanted to get some expert Alfa knowledge. I’m going to get some quotes from other garages tomorrow. Thank you in advance for all your help.

Are you any good with wiring?

If so buy a couple of looms and do the job yourself. Took me around 2.5 hours with a cup of tea in the middle.

Thanks for replying so swiftly mate. I will be totally honest, I haven’t a clue about wiring. I saw these two looms on eBay as well, are they generic Alfa looms, or are the model specific?
I’m considering buying them and paying someone to do it. But what do you think of the quote from the garage? Is that standard or a bit OTT?

They are specific for the Giulietta. I fitted the exact same ones to mine.

I can't see a garage or car electrician taking more than a couple of hours to do them, so maybe £150-200 would be fair depending on their hourly rate?

Okay mate, I really appreciate your time and information. That sounds a bit more economical than having the garage do it. Top bloke you are!

I've done a few of these on my own and my daughter's Giulietta plus those for friends. Also on Fiat 500 (daughter's previous car) and Mitos, again for friends. You don't say where you are so I cannot recommend any specialists. Any reputable auto electrician ought to be able to do it.The kits have the silicone rubber covered wires that are far superior to the original ones.
A search will reveal very many posts on this subject and how owners have tackled the work.

Thanks for taking the time to reply mate. I am based in Ringmer (East Sussex). I have checked out previous posts, that dated back a few years so I just wondered if this was still best solution and also an opinion on the price of the quote, because it did seem a bit steep. I’m happy to buy parts and pay someone or to pay a garage offering a more reasonable price.

I’m absolutely useless with cars, so I’ll see if I can find a kit with the silicone rubber covered wires. If not then I’ll opt for what the chap above recommended. Much appreciated mate.

The items linked above are silicone insulation so they are the ones to get. A local auto electrician will fit them no problem,as said above it’s fairly easy I did mine in couple of hours.

that quote above is far too expensive in my opinion,what are they actually going to do to repair it for that cost?

I haven't replaced mine completely but a while back my rear wiper started gong a bit mad so I had a look and a couple had snapped and a few others looked a bit worn, I stripped them back and extended and re-soldered myself and so far so good.

Problem with repairing just those that have failed is the others will follow. I've done a couple where it was a follow up to a partial repair.

Alfa2020, if you cannot find a local auto electrician you could give Mike or Gordon a ring at Day and Whites at Brands Hatch. A bit far for you perhaps but good work done there.

I just spoke to a guy who said he’ll repair the breaks. He also said he wouldn’t want to replace the looms as all of the wires are black, and he wouldn’t know how they match.

The garage wanted to replace both wiring loom harnesses and charge for 3/4 hours work (I assume) didn’t ask for a break down.

Broken wires are connected temporarily,; the way they break leaves 'witness marks' and other evidence. The wires are of a range of different AWG/SWG. Once connected temporarily the function is checked for correct option. Then each wire is replaced one at a time and that way they are not confused.
The only one that can be tricky is a co-ax cable in the right loom as the connections have to be done using a fine tipped soldering iron but the good news is that very often it isn't even connected to anything in the hatch! Many cars use the elements in the rear window for radio frequency devices such as telephones and t.v.s. I don't think there are many Giuliettas that use that co-ax, mine didn't.

Your guy says he doesn't know how they would match, so how is he going to repair those that are broken? Same as I've described in my first sentence. So from there he could replace each methodically.

Luckily for me the 3 that had snapped were of different gauges so I was able to match them up otherwise it would of been a real pain.

I had 5 broken wires, so I matched them up and marked them and then just replaced the lot one by one on each side with the replacment loom kits.

Exactly. It really isn't that difficult as some believe. Just a matter, as you say, one at a time and check each connection by pulling gently on the wire. Any decent auto electrician will be able to do it without fussing.

I have changed both of my looms before anything happened for peace of mind
The more wires are broken the longer it will take to change, as the original one are all black, and the cost will be higher as it will take longer to diagnose
If you do it preventatively before they brake, it will be cheaper
Win win

As soon as one broke on mine I changed all on both sides. I had the kits in my stock room (spare bedroom) ready and waiting.

Sorry a bit of a late response. I had my wiring done on my previous Giulietta and although the work was done under warrenty I did see the cost and it was £800+. This was an all new loom not these replacement sections and done at my local dealer.
