Hi. I didn't know where to place a discussion like this so I put it into a general one. I'm wondering if you have some experience where to buy cables for wiring harnesses with OEM specifications. I found some can bus twisted pairs on Aliexpress with fair enough quality but for the single cables I can't really find a good source. Do you have some suggestions where to find out? Thank you!

I am from Poland and I can without any doubts recommend https://wtyczkolandia.pl/ site. They offer automotive cables and also VAG connectors with very good quality and price. Unfortunately I don't know whether they send packages abroad and can communicate in other language than polish.

Just to let you know - you are looking for FLRY-B cables (Automotive low voltage cable (FL) with reduced thickness of insulation (R) made of PVC (Y), with irregularly stranded conductor (B)). List of the most used VAG connectors can be found here (with part numbers): https://www.drive2.ru/l/531220247940694476/

Thank you. Will definitely try them out!

Speaking about the connectors. I found some listing of commonly used connectors already but I still didn't find part number of the one used in the 5WA973708 connectors (Used in for the reverse camera). Im attaching some picture how it does look.

Any idea where I can get them?

It looks like MQS or MCON connector (depending on which side there is that "lip" on the top)

I think that those are different one. Its like half of those connectors (Width of that pin is 1 mm... Where MQS/MCON has 2mm). And it does not have a "lip on the side" but kind of "bridge" from side to side on the upper side of the pin hole. Here is a picture where it is more obvious..

It's nanoMQS. The crimping tool is expensive, I believe we paid around £1100 for ours a couple of years ago. There may be third party tools now but at the time the only option was from TE themselves

Is it so different to use the original crimping tool in comparison with some 3rd party tools? Is it worth the costs?
You may be lucky with a generic open barrel crimp tool, or it may just crush the crimp and cut the wire. I use Molex connectors in my job and we have 4 different Molex crimp tools: but it is essential for us to be sure that each crimp is perfect.

Almost year ago I have bought some cheap crimp tool from AliExpress (https://aliexpress.com/item/32859813451.html, model SN-48BSR) and I am really happy. For my "non-professional" (aka personal) usage it is far more better than pliers or any other tool. Here are image of that device and how crimped wire looks (don't judge me for the poor quality :ROFLMAO:)

Absolutely nothing wrong with using a generic crimp tool. If it gives good results there's no reason to spend 500 Euros when you only need to spend 20. And it will almost certainly give a better result than using pliers!

I've not tried any third party tools for nanoMQS so I can't comment on that

Looks.great for MQS, I don't think you'd get away with it for NanoMQS though
