Retrofit Keyless Entry

[pdcraft]

I tried to retrofit keyless go myself this weekend and have now given up. My problem was the wiring from the door to the A and B pillars. I wanted to go through the original feed-throughs. This might have worked at the back, but at the front it is almost impossible to remove the plug from the vehicle without breaking your hand or removing the dashboard. And after 2 days, I really didn't feel like doing it anymore.
If anyone has any tips or their own experience of how they solved it, please let me know, especially for the front doors.

Did you go for connecting own connectors and wiring directly to the CEM? Or exchanging the complete wiring harness with correct connectors already attached. 

Or did you do the latter and you still need to connect door to CEM?

I'm not crazy, I'm attempting to add the missing wires on my own. For the buttons and antennas in the doors. But the problem is currently the connection from the a and b pillars to the door. The rest of the work is pretty easy.
