Im swapping stuff over to my new engine and I've found a wire that is just hanging in thin air. I checked my other wiring harness to see what that one did and that one is loose too. It is red and black. Here is a picture. It is the wire by the bolt with the washer on it coming out for the water pump.

 

Check the wire to the water thermosencor that turns the fans on at 226 degrees. MY guess with out a book with me .

 

that was my guess...do all FDs have that? I know not all FCs did and it resulted in an extra terminated wire in about that spot.

 

All FDs have that sensor .

 

good guess. thats what it was. I'll just leave it off for the time being. thanks

 

IT COULD BUT THE TEMP SENSOR ON THE LEFT REAR OF THE BLOCK.
