Various Electrical plugs and relays for BCM Max upgrade

Post by mfourc »

Hi All, I've BCM ending 087 in my car and want to upgrade to the 90 Max to get auto lights etc. It looks like I need to create a loom or two for this. That is not a problem for me but where is best to source all of the various plugs and relays from and if its VW direct, does anyone have the part codes?

as an example; I'm looking to do stuff like this https://www.uk-polos.net/viewtopic.php? ... 23#p516196


many thanks

Martin

Have a look here for the names:

You can buy repair wires from VW, very pricy.
Or buy separate contacts, i.e. on ebay, aliexpress, local hardware shop.

Yes, scroll down on a4 freunde to Dichtungsübersicht for the isolation rubbers

And for the terminals, look in ETKA or i.e. http://www.passatplus.de/umbauteile/stecker/stecker.htm / http://www.passatplus.de/umbauteile/ste ... ecker2.htm
