Did someone say CAN bus???? That's been my area of research for the last 3 months

The turn signal stalk is wired to the BCM.
When the turn signal stalk is signalling a turn, the BCM flashes the external turn signals and broadcasts a CAN message, that is received by the combination meter/gauge cluster which turns on/off the gauge cluster turn signal.
The CAN ID for the turn signal is 0x60D (BCM), second byte, bit 6 for right turn / bit 5 for left turn.
