Pulled the parts catalog and took a look. From what I could tell, the istrument panel section of wiring (the bulk of the package in the dash) has no specific option for with and without overhead console. There is an option listed for the part running up to the overhead. So, with a service manual you may be able to splice in at the main harness. My truck doesn't have the console, but has the mount for the temp sender behind the radiator, so some parts are there.
