Important — 2008–2011 Peterbilt 389 compatibility
JW Speaker Model 9600 headlights may not be compatible with the truck’s CAN-bus/lighting control module (LCM). BTS advises that these model years lack LCM LED-mode programming, so dealers cannot program out the resulting errors as they can on newer models. According to BTS’s current product guidance, JW Speaker is aware of this issue and currently has no fix. The separately sold harness is a wiring adapter only and will not resolve this compatibility issue. Contact BTS before purchasing for a 2008–2011 Peterbilt 389.
