chances ar ethat one is a coolant level sensor and the other is the one you want. I would guess the single wire sending unit is the one you want. To test, simply unhook the wire and check for temp lights, then take a jumper wire and ground the stud directly to the frame somewhere, recheck for lights. If this is the temp sending unit, you'll get a temp. warning light on the dash. If I am wrong, you'll get a coolant level warning light on the dash. These tests are harmless and very easy to do. That's what I do at work anyways. It seems to work on chevs and diesels. Make sense? or you could do the ssame tests with the truck running and the temp sending unit will be tricked into turning the fan on! Then you'll know for sure.
