Retrofit Keyless Entry

[Aliaksandr]

Rear door connector.

---

I have completed the installation. I bought and painted 4 handles. I bought 3 antennas. I bought 90 meters of 0.25 wire. I did the wiring of the rear doors. These are 2 wires for the antennas, 1 for the handle and 2 wires for power supply of the hand inside the door. I did the wiring of the front doors. Wires for the handle. 2 wires for the antenna in the back. I connected all this to the CEM. There was a problem with the contact of the right antenna and CEM. After eliminating it, everything works. Thanks everyone.

I have now succeeded with my keyless retrofit. 
It's been a long way coming to this point. I would for the sake of the projects budget and your mental health (searching all pins and connectors is tormenting)  try to aquire everything at a junkyard. 

What you will need:

FR, FL, RR, RL door harnesses from a car with keyless (it's technically possible to add pins to your harnesses but you will need to find donor/names of these terminals and connectors and pin them onto your own harness, front harness connector is also very hard to open. 

One front and one rear cut pillar connector (id recommend an extra rear connector if your connector doesnt have enough pins / you damage pins during extraction) 

4x handles with LED (all handles with LED have keyless) it's very good to buy these from a junkyard as you will not need to buy new handles + paint.

3x antennas, these can be any antennas you can get hold of. 

1x antenna holder (as mentioned in the beggining of the thread, it clicks in nicely under your trunk floor)

Cut harnesses from a junkyard cars CEM (FL and F0) (fun fact, F0 and D connector for your speakersystem are the same) 
My aliexpress link i posted here fits both these terminals) FL however i had to extract from a cut harness from another car. 

I understand now that a guide will be pages and pages long as there are so many parts to this, like how to remove all harnesses and everything from all your doors, how to rebuild the door again etc etc. So i'll just offer help to anybody else needing help explaining any part of the process that might take a while to grasp ( i myself have read this thread atleast 20x times just finding new peices of information i missed/did not understand at first. )

Thank you for the proper info. 
I would like to retrofit this on my xc90 2017 and i have sourced the following:
- 4 x handles with LED
- 3 x antennas
- all 4 door harness .
- all CEM connectors

What i don't understand is this part: 
 - One front and one rear cut pillar connector

Can you be more specific please ? or a picture ?

Also what wires do i need to run to the CEM ? I saw the picture related to CEM but dunno what i need to run there ...

Thank you !

Sorry i did not get a notification that i was quoted.

So the pillar connector are the connectors that are are on the car side that match up to your doors connector. If you can visit a junkyard and cut these and extract pins you can connect these to your wirings that lead to CEM.
You need to run all four doors and three antennas to cem.
