Since my car is a 1992, I couldn't use a traditional KITT lower console because the stock center console is more narrow in the '92 as opposed to an '82.
My lower console is a custom job made by me from an aluminum project box. I relocated the stock switches for mirrors and windows to it. The console controls power to the switch pod unit, voice box disconnect, and surveillance mode. I integrated the surv. mode electronics into the lower console. 
I will likely eventually swap out the entire stock center console unit with an older style one, so that I can use a more accurate KITT lower console. But for now, my little custom job is working fine.
Update 7/09 - I've finally gotten all the pieces together for the 'new' center console. I've been working on cleaning them up a bit to get the pieces in better shape for my car. I have an order in with Advanced Desings to get a 1st season style lower console. The install of the center console and the KR lower console will likely be a winter garage project.
