So I pulled my 6.5 turbo motor and replaced the bad head gasket. Unfortunately due to several reasons the motor was out for a month and a half and my memory was a little fuzzy when I went to put it back together. It is all back together and sounds great but I have a sending unit that I can't find a plug for. My temperature gauge does not work and I think it has to do with the sensor on the rear of the passenger side head not being plugged in. I have been over the wiring harness several times and can't seem to find the plug lead. Can anyone tell me where the plug wire comes from? I'm pretty sure the truck had one when I pulled the motor and now I'm going crazy trying thttp://www.dieseltowingresource.com/images/smilies/confused.gifo find it?
