jamesinc @volvo1975 do you mean the one with the unusual two prong plug that sits up near cylinder #4 on the intake side?
jamesinc Well, this is the sensor I think you're referring to, though I didn't think there were any 740s that had it... https://www.ipdusa.com/products/7799/106480-cold-start-thermo-time-switch
