I'm probably in the next week or so I'll probably take it to Toyota for all the oil changes etc. I just don't want to walk in there blind and have them run me for a loop. I'm pretty mechanically inclined but I just need to know if this is totally out of my league. I will check for any electrical connections only if I know where I'm looking. I appreciate all the help that your giving me.

Unfortunately, the diff cooler was never offered here in the US. As a result, my TSRM (Toyota Supra Repair Manual) does not have any additional information on this feature. If you can read Japanese, I would strongly suspect that, since you're located in Japan, getting a Japanese TSRM for your '95 TT from any Toyota dealership over there should be no problem. You probably only need Volume#2 (Chassis). This is probably the best source of information for not only the location of diff cooler components, but also a set of troubleshooting steps to diagnose problems with this subsystem.
