I bought a superlift speed sensor calibrator for my 2000 TLC becasue i run different tire sizes.
Installation was pretty easy, but it took time to study the EWD until we found the speed sensor wire and connector (see pg 242 of 2000 model year EWD). Then we went hunting behind the glove box for the right connector, realizing after an hour of looking, it was staring us straight in the face. There must be hundreds of similar shaped and colored connectors on these things!
We drilled a hole in the glove box like Slee did with an 80 on his web page, and put the unit in there. We used a GPS to calibrate the speedo to two sets of tires 295/75/16 bfgoodrich AT and 265/75/16 Nokian winter studded tires. Took some fiddling on the unit to get the calibrations right but it all worked out.
two pictures are from the EWD. the connector IX1 has the speed sensor wire (R-G) color leading to PIN 7 from the sensor on the transmission after passing a EB1 "engine bay 1" connector. Bottom picture is the connector's location behind the glove box. It is to the left of the ECU, slightly to the front. You do not have to remove the ecu to do this!
After making the R-G cut, calibrator has 4 wires, Green to the Sensor side, yellow to the connector, power (red) -- there's lots of 12v acc sources back here, and black for ground.
