I have an 06 Passat and it requires a can-bus adapter for the R.A.P. I think the Eos requires the same. As far as the VSS, this may also be in the can-bus, I know it is on the Passat. I didnt want to shell out the money for a can-bus adapter but I found the VSS output on pin 28 of the cluster. I dont know if the Eos electrical is anything like the Passat, but it may be similar.
