new temp gauge, doesnt seem to work Options

[7391420]

I've posted this a few times, and after trying several methods it's still not working..

-new vdo temp gauge-with the numeric readout.

-It plugs right into the old plug but it's not reading anything after driving the car for a while

-the old gauge worked (so i know the wiring is good)

-I did at the time buy a new VDO temp sensor, do I need to install this to get the gauge to work? can I remove the old one and plug this one in? or do I need to fabricate a place to plug it in and wire it up?

I went through the same thing. Two of the wires in the plug need to be reversed. If you look at the wiring diagram that came with the new gauge, and you look at the letter designations marked on the back of your old gauge, you'll see the two that need to be switched. I'm sorry I can't recall which ones they are--IIRC it's the sense and the light, the ground stays the same???

You will need to install the new sensor to make the gauge work, obviously after draining the oil. It screws right into where the same spot as the original without modification and you can use the existing wiring. Doing the sensor was the easy part! Figuring out the reversed wires took a little head scratching.
