I used a plug that goes in the cig lighter for a temp installation.. of course finding time to hook it up correctly is the hard part. Mine is an electrical guage I bought through JC Whitney, and its digital. I have noticed one little problem. If I turn on the head lights, the temp will go up about 5 degrees. and if I turn on the AC it will go up about 25 degrees. Even just turning the fan on will cause the temp to read higher. No doubt that their is just too much draw of current/voltage/whatever... so the temp guage is sensing less voltage going through the sensor and is assuming hotter tranny fluid. I plan to fix this by doing the wire mod for the altenator and battery... again .. when I find the time. Hopefully that will fix it. If not.. then I will probably run a piece of hevey duty wiring straight from the battery, through a relay, and to the guage.

Hope any of this helps...
