Hello everyone, that's my first post here.
I'm waiting for my uaefi to arrive and I have bought an LSU 4.9 sensor but I realised that it doesn't have a wire connected on pin 5 (but the pin is present on the connector) which is the calibration resistor. I have measured the resistance between pin 5 and every other pin and have found that there is resistance of 285ohm between pin 5 and pin 1 (red wire). Every wire is connected per instructions on the corresponding pin on the connector except pin 5 (green wire). Can I use this sensor as is, does it need any modifications or is it incompatible?
Thank you in advance!

Re: 5-pin LSU 4.9
Please connect six wires to the six pins on the connector. Congrats on locating calibration resistor which is part of the sensor connector!
