I have four wires left over from pinning the 54-pin(X695) TCU connector to the 26-pin(X34130) Combox Telematic connector.

The remaining wires from the TCU are:

Pin Description
--- -----------
3 Switch-on signal for battery charging (Cradle On)
ON signal for the charger electronics in the snap-in
adapter

24 Signal from wheel speed sensor, front left
25 Signal from wheel speed sensor, front right

46 Signal from transmit/receive button (Cradle Key)
Call accept/transfer/paring button


Does anyone know where these pins from the TCU map to the Combox? The wiring diagrams that I have seen does not indicate a mapping for these pins.

Hi, did you manage to figure out all the pins? If so could you please send me the info? Also did yours have MULF2 & TCU?

I have the TCU only...

Here is the mapping from TCU to combox:
