OBD-2 was required by federal law beginning the '96 model year, so your 2000 will use a regular OBD-2 scanner, and, I'm pretty sure, the port should be under the steering column. I'm not familiar with EEC-V/OBD-2, but I'd probably start by checking for the power/ground to the diagnostic port. You might post this in the EEC-V forum where someone more familiar with your system can help.
