how do you guys wire your trans temp gauge? what acc do you splice into?

 

Well the power for the light will go to a switched 12v source such as your headlamp switch.. Where are your gauges moutned? the pillar? then the switch is the best way to go.. if it's down in the console i'd suggest your ash tray bulb.. Ground obviously goes to ground.. The power for the gauge itself will be tapped off a Ign 12v which can be found on the back of your radio or under the dash.. really easy if you have a test probe... Don't have my car or id give ya color code's. And the sensor is self explanatory..
