My recently bought Citigo did not come with rcd215...instead there was a Pioneer headunit installed..So since I am planning to retrofit PID, I need to have the stock rcd215 in its place...

Yesterday I removed the Pioneer to check the wiring...comparing it with the wiring diagrams, everything is there, besides the 2 canbus wires (high and low)...

These are the B397 and B406 wires that go to pins T73b/20 and T73b/21 on BCM respectivelly.....

 

Since I do not want to to remove BCM yet (I will eventually , when I retrofit cruise control), I was wondering if it would be ok to solder them on the exactly same wires that run from OBD port to the same pins on BCM...

 

I have noticed that even VW on PDC retrofit kit is doing something similar ..instead of running wires all the way from pdc control module to BCM, they instruct to solder them on the same wires from airbag control unit under center console (that eventually run to BCM).

 

So can anyone with more experience in electrics, confirm that my idea will work without any problems??

There are multiple separate CAN-buses in your car.

 

When adding a module, it needs to be on the correct CAN-bus.

 

The OBD port is the diagnostic CAN-bus so it cannot be used for the radio.

thank you for your reply...

 

I understand what you say but the reason I searched and chose those wires is that they are exactly on the same route and goes to exactly the same pins on BCM...(also they are exactly the same color and same thickness...)..

 

The 2 wires from rcd215  are orange/green and orange/brown and go to pins T73b/20 and T73b/21 on BCM 

The 2 wires from obd port are also orange/green and orange/brown. and also go to pins T73b/20 and T73b/21 on BCM

If you're sure that the WD is correct, try it and see what happens

 

It shouldn't damage anything if it's all just CAN-bus.

I used the wiring diagrms from skoda citigo workshop manual so i believe they should be correct...all other wirings I checked in car are as shown in the diagrams..

I will try as soon as I receive the rcd I just ordered and post update here....

Does anyone knows which of the repair cables that skoda sells, fit in the particular 8pin plug of the rcd215?

I would prefer to buy a few of those and make extensions rather than make my own..
