Retrofit Keyless Entry

[Pliind]

https://mk4-wiki.denkdose.de/artikel/bcm/bcm_ausbauen there is a very similar Ford Plug and in some kind of forum they found out that these are just standard 0.64 Pins in there
https://mou.sr/3v6O9c0 maybe these?! i've ordered 100 of them so i can test but currently i need my car
As i can see you guys managed to solve my a and b pillar issues. I have vacation in 2 weeks, so I will tackle the project again

Welcome back to the jungle   I'm happy you have not given up all hope yet. Please get back with feedback on the last pins it will be the last peice of the puzzle. 

Also during my inspection of the harnesses i think it's possible if somebody wants to do a shortcut they can use the hole in the door connectors where the mirror cameras cable should come through (only works ofcourse if you do not have cameras in your mirrors..  )

  the harness i bought was with camera so this is occupied but for somebody just pulling the one wire through it is an option.

Here is the part number 30656698 for the repair terminal you need for the most part of the CEM connector.  Check this out for the other two types.  The bigger ones are for high amp circuits. Yours is just a signal same as the parking sensors.

So you are saying the 2 for the rear antenna in the FL connector are the same as the one in the FO connector? or would it be 30656637?

The part number 30656698 is the smallest PIN on the CEM connectors. "The purple side" of the connector (from the picture above).  The blue socket has two sizes and  part 30656637 goes to blue side. Now, I don't know which side you need to connect for your retro fit all the three connectors have the same three sizes.

It's the purple side. So it should be the same terminal in FL and FO in other words for the keyless retrofit.
