I feel dumb asking this but here goes. I had the tstat housing changed due to leaking a year or more ago on my Sportrac in my Sig. I was dinking around last night as I had to change the pressure switch on the master cylinder to fix my cruise and noticed that the sensor on the thermostat housing on the drivers side was unpluged and I can not seem to find an open connector for it. Does anyone know what harness it comes off of? I have not got any warning lights and truck is running well.

Thanks

 

Well I may have found an answer. After further research I guess there is a single sensor and a two sensor housing. Evidently my truck had the single sensor but the shop that did the work used the two sensor unit and the extra senser is just and expensive plug.
