Wayne,

I just found a wiring diagram on the net and see that the connector i 
was looking at was for the lights only, and not the CAN-bus module. 
There is another 12-pin connector that I didn't see that I need to wire 
up some of the pins on to get it to work. The original console I have 
only contains reading lights, while the one I am installing has the trip 
computer, etc., a totally separate module, in addition to the lights.

Thanks for your reply.

Peace,
Pat
