HI guys I just installed my HKS TT Type 0 under the A/C unit where the empty section is in the center of the DASH. I had to drill a hole in the back of the Center piece (Removable), just enough to get the Plug from the TT through. It was easy using a dremel. The whole process from end to finish was about 1 1/2 hours. I also had the HKS Wirie harness, which made life easy. I have a pic as well, enjoy. PLease let me know what you think.

 

nice & clean,good work
