UHI conversion pinout for D2B (W220 example)

[miro]

I have a W220 and W203 conversion to make into UHI. Can you share with me the pin location of the wires from 10pin RJ header to 10pin AMP connector.

I purchased over the weekend the part numbers for the connectors used in the UHI harness joiner inside the armrest.

001 545 59 40 housing 10 pin
000 545 93 03 cap
000 545 46 30 plug 10 pin
000 540 45 05 pins

168 545 43 28 plug

I didnt order the pins since they are normal MQS type used in all installations.

Did anyone publish the conversion pinout yet ?

I can publish now the pin colours for wires at the first joiner after the UHI connector back to the PSE.

Colours may vary but the pins dont since all UHI connections are valid from PSE to armrest no matter what colour wire.

So now you have the data connectors working and the antenna is still some stinky old technology.

What you need
--------------
SMB-FAKRA connector (female) from Amphenol / Molex / Tyco.

What does it look like ?
---------------------
A normal SMB connector with a custom made plastic shell.
In this case it is type D cover = Bordeaux Violet

Note
-----
I have chosen to modify the wiring harness that resides in the car not the harness that is being added with the UHI connector. I am keeping that as original UHI spec and deleting the outdated style of connector.

It would be easier to buy a mini-UHF connector and splice it onto the RG68 cable that comes with the UHI loom, but that seems ancient to me.
