This is kind of a long story but to I'll try to keep it brief.

I'm retro fitting bluetooth to my 2001 540 Sport that has SatNav/DSP/Moto V50.

I now have the "special adapter" wiring instructions to allow me to adapt my current wiring loom to plug in to the bluetooth ULF ( Bluetooth control unit ) but need to get the correct connectors to allow me to make up my adapter.

The three connectors I need are
X400 plug
54Pin Plug
Male 25DB Serial type connector.

Obviously the Male 25db connector can be sourced from anywhere are it's just like a PC Serial connector but I'm struggling with the other two.

I have spoken to BMW and they do supply specific connectors but they are unable to identify the correct parts without part numbers.

Trust me when I say I've spent a lot of time on places like realoem.com and TIS and can't find the parts either.

Can anyone help ?

Heres a picture of the offical loom ( again which I can't find a part number for or I'd buy this and adapt it ) that comes part of the BMW OEM Bluetooth Upgrade fit that has those correct plugs on.



This is a picture of the modifed version of the OEM supplied loom by Martin @ Bimmernav. The connectors I'm after are 5a and 5e



So in summary, if anyone can help me track down these two connectors then great, or if anyone can help me track down that original OEM bluetooth wiring loom then also great.

Thanks for looking
