[Shop-talk] 06 Caravan wiring help needed

[Wayne]

Are you sure it needs more wire? CAN-Bus has been common for nearly 20 
years now, and cars blip network packets over power conductors, rather 
than running separate conductors for every device. Even if it was 
hard-wired, I doubt they would have two different harness stocked on a 
'line just for one optional feature.
