[Shop-talk] Truck instrument cluster, dash, and parking lights died

Scott,

I'm not sure what it would entail (or even if it's possible) but can you 
put the stock radio back in for a test?

Some of these CAN systems get crazy when everything isn't 100% like it 
wants.  Especially if there are 'tie-ins' from other systems (I think you 
said the radio dims with the headlights).

If it's a matter of removing some dash and changing out a harness, it 
might be worth trying.  If you had to cut and splice wires to do the 
install, it may not be worth it.

Just a suggestion.
