Re: One temp sensor for gauge and PCM
I did play around with the calibration resistor on the back of the gauge, but the stock 90ohm one gave the best overall result thru the usable range of the gauge.
I attached some diagrams. Pin C is the one you tie in to the green wire in your original harness. A&B are tied to the PCM wiring.
