Hello all. 2018 fiat 500x with blanks under the door panel where puddle lamps would go, there is wiring there but they do not seem to have power. Ordered some online and was hoping for plug and play. Anyone know where the wires should get power?
Do you know if there are varying BCM options,The Puddle lights are driven/controlled directly via the Body Computer (BCM)
They will most probably need activating in the BCM.
The BCM is in many respects a mystery. Being essentially a computer controlled unit then different firmware can be installed. Whilst if you like it has say x I/O lines plus the various CAN and serial interfaces what they can all do it determined by a) the version of the BMC and b) the installed firmware. On top of this you have the infamous PROXY confirguration when bytes within a control block determine what is supported and specific functions.Do you know if there are varying BCM options,
(Like my frustrating attempts to upgrade my Cruise Contol.. " wrong option of kit")
