07 canyon 5.3 swap/ temp sensor and gauge not reading correctly
I have a custom harness with the 3 pin plug and the 3 pin sensor, but when I look at my stock temp gauge (low-high) it shows 3/4 temp and I shut it down. I then hot my remote temp gun and the headers only say 200 degrees. My heads should be even less at the same time I would think. I'm using a 165 thermostat. What could be my problem and how do i fix this? Dual electric fans using the custom harness with relays and the e67 ecu to control them, but they do not turn on, I think because of the temp setting being higher in the ecu and the difference in readings.

I just got a Bluetooth obd2 device and I'm reading Temps on my phone. The gauge is off, but not by as much as I thought.
Thanks for your reply and help
