open egt thermcouple
 

when I was installing my fuel pressure gauge I turned the key on to make sure it was hooked up correctly I noticed that my banks big hoss tuner was throwing a code. Open egt thermocouple. I checked the wires that go to my pyro gauge and they are not hooked up to the banks tuner, just the gauge. Is there a factory egt thermocouple connection and where is it located? I checked in my repair manual but did not see anything. Also will the box still work when it is flashing a code or does it set it back to factory settings? Appreciate any info I can get. thank you
