Just for recap when the Ccd connector is plugged. The ABS light, and airbag light come on, followed by the Engine light with No bu5.

 

so adding another load to the CCD bus wires causing 2 other CCD bus wires to throw a code. I would say either bad CCD wiring somewhere or bad PCM

 

Would it affect the radio as well because the radio still was functioning.

 

It shouldn't affect the radio

 

for the head light switch, when it dims, would it be an all or nothing concept? (Radio, gauge cluster, and Overhead)

 

should be all or nothing unless it didn't light up to begin with

 

Okay, The console did dim before, at the time the harness was not put in the dash. Also worked the 1st day after I drove it home along with the CCd working.

 

Check the wiring or you're console somehow went bad

 

Background : the wire harness has 2 connectors, 1 brown plug, and one white plug for Ccd. I got the new harness today, I plugged in the Ccd plug (white): Gauges went to their proper positions, and no problems occurred. However the brown plug wasn't connected, because the other one was plugged in. Does it need to be plugged in for the test to be valid?

 

Post pictures of the back of the console and the plugs for me
