I just bought myself this really cool new gadget. I plugs into the ODBII port and with the 6ft cable was able to route and place it on left side of dashboard. I've set up two of the open memory Xgauge registers with Trans Fluid Temp and Boost pressure. Allows me to monitor 4 Digital Gauge readouts simultaneously...TFT, PSI, ECT & EOT.
