I'm running dual E-fans on mt '93 XJ (4.0l, 5spd, mostly stock) and I have a lower temp thermostat installed. Currently its a 160f, but I will be going to a 180f once the cooling system is all sorted out.
I would like to put my e-fans on a temp switch instead of the current manual switch, and I have found some aftermarket temp switches that are in the temp range I am looking to run (185F+/- On - 170F+/- Off). These are single prong grounding temp switches that would thread into the thermostat housing (3/8th NPT)
similar to this one:

I have noticed however when I unplug that temp switch, the Check Engine Light turns on. I do not want to have the CEL light on all the time! I also do not want to lose my temp gauge functionality.
My questions:
Which of my two temp sensors sends a signal to the temp gauge in the dash?
What functions does the temp sensor in the thermostat housing serve (1993 model)? Can it be replaced?
If the temp sensor in the termostat only runs the fans, can I replace it with an aftermarket one (as above) but leave it connected to the stock harness to avoid the CEL?
Thanks in advance!
