If you look at the top of the water pump, just below (to the passenger side) the outlet hose to the heater core is the port the water sending unit goes.
alright, ill hook it up tomorrow, if i can, why would you have to drain the oil if the sending unit is ontop of the engine. were does the volt meter go on the truck, and is the 1st annual in 06 that has already passed or 07 which is coming up
