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? - |

VDo temp gauges are matched to a specific sender. If the gauge is a different model that the old one and it sounds like it is then you can contact VDO, give them the number that is on the body of the gauge and the tech can tell you what sender you need. I recently had this same problem since my 4 cylinder race engine blew at the CA Speedway and the oil temp sender went flying. We tried several senders, even the one recommended by VDO and could not get accurate readings. VDO said to put a 1k pot in line with the sender wire, get the engine real warm, measure the oil temp and then adjust the 1k pot until the gauge matches the actual oil temp. Remove the 1k pot, read the resistance and add a resistor the same amount. I did this and have accurate readings now. I probable should have bought a set with the gauge and matched sender, but since the one I had was made in 1978 I wanted to keep it......You can do a search on the net for VDO USA to get their number, nice people. Good luck
