Hi guys,

My original fuel sender was leaking around the positive contact. I replaced it with a 2 pole sender from ZCD. Since I lost the 3rd contact for the thermistor (low fuel), I only used 2 wires (pos and ground). The fuel gauge is working (I do need to bend the float's arm - I have 12 gallons there, it is showing barely half full).

Now my floor temp light is always on (cranking/driving). My model is CA, I still have the sensor/catalytic converter installed. The sensor used to work. I checked the electrical diagrams - the dash lights for Floor/Fuel Warning are sharing the same wire.

I am not sure why the fuel sender's wire would affect the Floor temp sensor's bulb? The only thing I haven't checked is the floor sensor's relay under the passenger seat. I probably can ground the sensor's connector in the back to see if the light goes out - this should verify the relay's operation. Any other ideas?

Thanks!

Correlation does not imply causation. What you leave out, though, is how you adapted the harness to go from the Yazaki round terminal plug to the individual wires. What did you do with the yellow/blue wire?
